Answer:
75
Step-by-step explanation:
With reference angle 53°
base (b) = 45
hypotenuse (h) = K
Now
cos 53° = b / h
0.6 = 45 / K
K = 45 / 0.6
K = 75

Triangle ABC was reflected over line m, then dilated by a scale factor between 0 and 1. Which diagram illustrates these transformations? Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime Triangle A B C is rotated about line m and then dilated to form smaller triangle A double-prime B double-prime C double-prime Triangle A B C is reflected across line m and then is dilated to form larger triangle A double-prime B double-prime C double-prime Triangle A B C is rotated about line m and then dilated to form larger triangle A double-prime B double-prime C double-prime
The transformation is better described by: Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime
What is transformation?In mathematics, transformation is manipulating a figure on a plane or coordinate system.
In this case the manipulation involves reflection and scaling to a factor between 0 and 1
scaling to factor 0 means the triangle disappeared
scaling to factor 1 means the triangle remained same size
factors between 0 and 1 means reduction of size.
since the transformation did not rotate the triangle it makes the first option the correct answer

Answer:
60 degrees
Step-by-step explanation:
angles on a straight line add up to 180 degrees.
so do 180-115=60
because its an equilateral triangle, you can check whether it adds up to 180

A painter leans a 30 foot ladder against one wall of a house. At what height
does the ladder touch the wall if the foot of the ladder is 10 feet from the base
of the wall?
Answer:
20ft
Step-by-step explanation:
The height at which the ladder touch the wall when the ladder is 30 feet long, and the ladder is 10 feet from the base of the wall is 20√2 feet.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
Consider the diagram below.
We've got:
Length of the ladder = |AC| = 30 ftDistance between ladder's bottom and base of wall = |BC| = 10 ftHeight of wall from base to the point where ladder touches = |AB| is to be known.The wall is usually perpendicular to ground, therefore making 90° angle with it. Thus, ABC is a right angled triangle.
Using Pythagoras theorem in it, we get:
[tex]|AC|^2 = |AB|^2 + |BC|^2\\\\30^2 = |AB|^2 + 10^2\\|AB|^2 = 900 - 100\\\\|AB|^2 = 800\\\\\text{Taking sq. root of both the sides}\\\\|AB| = \sqrt{800} = \sqrt{ (\pm 20\sqrt{2})^2}\\\\|AB| = \pm 20\sqrt{2} \: \rm ft[/tex]
But as length cannot be a negative quantity, so we get:
[tex]|AB| = 20\sqrt{2} \: \rm ft[/tex]
Thus, the height at which the ladder touch the wall when the ladder is 30 feet long, and the ladder is 10 feet from the base of the wall is 20√2 feet.

What is the value of value of 5/6 ÷ 3/4?
Answer:
answer is 10/9
:-)))☺️☺️
I hope it helps you
Answer: 1 and 1/9
Step-by-step explanation: Here, we have 5/6 ÷ 3/4.
Dividing by a fraction is the same as multiplying by its reciprocal.
In other words, we can change the division
sign to multiplication and flip the second fraction.
So here, 5/6 ÷ 3/4 can be rewritten as 5/6 × 4/3.
Now we're simply multiplying fractions so we multiply across the
numerators and multiply across the denominators.
So we have 5 × 4 which is 20 and 6 × 3 which is 18.
Notice that 20/18 is not in lowest terms so we divide the
numerator and the denominator of 20/18 by 2 to get 10/9.
If you would like, you can change this to the mixed number 1 and 1/9
by simply dividing 9 into 10 and putting the remainder over the denominator.

Billy and Tom are out to dinner. Their bill comes to a total of $100. They have a 15% off coupon but tax and tip must also be included. The tax is 6% and is applied before the 20% tip. If Billy and Tom want to split the bill, how much will they each have to pay?
1. How much is their bill after the coupon has been applied?
2. With the coupon applied, what is their new total (including the tax)?
3. With their new total, Billy and Tom can now determine the tip for their server. What is the final total, including the tip?
4. What will Billy and Tom each have to pay to split the bill evenly?
Please answer labeled with numbers! thankyou!
Answer:
1. $85
2. $90.10
3.$108.12
4.$54.06
Step-by-step explanation:
100-15=85 (15% of 100 is 15)
6 percent of 85 is 5.10. So 85 + 5.10=90.10
20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12
Now divide by 2 to get how much they each will pay 108.12/2 = 54.06
