The height of the isosceles triangle is h = [tex]\sqrt{a^{2}-\frac{c^{2} }{4} }[/tex]
Given,
Isosceles triangle;
An isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.
Follow these procedures to determine an isosceles triangle's height:
The lengths of the two equal sides are squared.Step 1 is then reduced by the square of the unequal side length, its result being divided by four.The outcome from Step 2's square root.The height of an isosceles triangle is the outcome.That is,
Height, h = [tex]\sqrt{a^{2}-\frac{c^{2} }{4} }[/tex]

ABC is a straight line. Work out the size of the angle marked x
Answer:
x = 57°
Step-by-step explanation:
angles on a straight line add up to 180°. to work out x, we need to subtract 70 and 53 from 180, to get the remaining angle, aka angle x. 180-70=110.
110-53= 57. therefore, x = 57°.
The measure of angle x in the straight line ABC is 57 degrees
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram:
x + 53 + 70 = 180° (sum of angles in a straight line).
Hence:
x = 57°
The measure of angle x in the straight line ABC is 57 degrees

At the grocery store, Henry bought c pounds of cashews for $4.99 per pound. If he buys 2 pounds, how much will they cost?
The cost of 2 pounds of cashews will be;
⇒ $9.98
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
At the grocery store,
Henry bought c pounds of cashews for $4.99 per pound.
Now,
Since, Henry bought c pounds of cashews for $4.99 per pound.
Hence, The cost of 1 pound of cashews = $4.99
So, The cost of 2 pounds of cashews = 2 × $4.99
= $9.98

Use the circuits shown to solve each of the following:
Answer:
1. R = 8 ohms 2. V = 32 volts
Step-by-step explanation:
1. We have,Voltage, V = 16 V
Current, I = 2 A
We need to find the resistance of the circuit. Using Ohm's law,
V = IR
So,
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{16}{2}\\\\R=8\ \Omega[/tex]
2. Current, I = 8 A
Resistance, R = 4 ohms
We need to find the voltage of the circuit. Using Ohm's law again,
V = 8 × 4
V = 32 volts
Hence, this is the required solution.
y’all please help. thank you.
Answer:
The answer is G.
Step-by-step explanation:
help please!! find the area of each triangle. round intermediate values to the nearest tenth. use the rounded values to calculate the next value.
Area of a triangle = (1/2)*base*height
For both of the triangles, you have the base (8.8 for the triangle on the left, 7.6 for the triangle on the right) and the side lengths, but not the height. But since both are isosceles triangles, you can find the height using the pythagorean theorem.
5.
First divide the triangle vertically into two triangles (see attached picture). Now you have two right triangles, you can apply the pythagorean theorem on either one of them to find the height. The pythagorean theorem says that for a right triangle, [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse and a and b are the sides of the triangle.
Substituting the given values and rounding to nearest tenth:
[tex]a^2+b^2=c^2\\4.4^2+h^2=10^2\\h=9.0[/tex]
Now that you have the height, you can find the area of the entire triangle.
A = (1/2)*base*height
A = (1/2)*8.8*9.0 = 39.6
6.
Same procedure.
[tex]a^2+b^2=c^2\\3.8^2+h^2=10^2\\h=9.2[/tex]
A = (1/2)*base*height
A = (1/2)*7.6*9.2 = 35.0

y = 3x – 10
y = 6x – 22
Answer:
x = 4
y = 2
Step-by-step explanation:
y = 3x – 10 (Multiply by -1)
y = 6x – 22
y = 6x – 22
-y = -3x + 10
0 = 3x - 12
3x = 12
x = 4
y = 3x – 10
y = 3(4) - 10
y = 12 - 10
y = 2

Maria needs to reach a window that is eight feet above the ground. When she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house. How long is the ladder?
Answer:
10 feet
Step-by-step explanation:
Given that the distance to be reached is 8 feet above ground and she she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house, the length of the ladder considered with the other lengths forms a right angled triangle.
The length of the ladder represents the hypotenuse side hence using pythagoras theorem
F^2 = 8^2 + 6^2
where F is the length of the ladder in feet
F^2 = 64 + 36
= 100
find the root of both sides
F = 10 feet
The ladder is 10 feet long
