The diagonal of a rectangle is 13 units. One side of the rectangle is 12 units. Find the length of the shortest side of the rectangle.
Answers
Answer:
Diagonal of the rectangle = 13 units c =13
side of rectangle = 12 units a = 12
area of the rectangle = l× b
In rectangle all the corner angle is 90 degree. A diagonal of the rectangle forms two right angle.so we use Pythagoras theorem.
formula ; a²+b²=c² a = 12 , c = 13
12²+b² = 13²
144 + b² = 169
b² = 169 - 144
=25
b = 5 units
a = 12 units

It takes Carol 30 minutes to drive to work using two roads. She drives 24 mph on a small road for hour. Then she drives 56 mph on a highway for hour. How far does Carol travel to work?
Answers
Complete question :
It takes Carol 30 minutes to drive to work using two roads. She drives 24 mph on a small road 1/2 for hour. Then she drives 56 mph on a highway for 1/4 hour. How far does Carol travel to work?
Answer:
26 miles
Step-by-step explanation:
The distance traveled is given by :
Distance = speed * time
Distance covered on small road :
24 mph * 1/2 hours = 12 miles
Distance covered in highway :
56 mph * 1/4 hours = 14 miles
Total miles traveled = 12 + 14 = 26 miles

Answers
Answer:
[tex]\boxed{x=73.74}[/tex]
[tex]\boxed{y=16.26}[/tex]
[tex]\boxed{z=25}[/tex]
Step-by-step explanation:
Hello there!
Algebra 1
The first thing we should find is the missing angle
Because this is a right triangle we can solve it using the Pythagorean Theorem
The Pythagorean theorem states that the sum of the two legs squared equal the hypotenuse squared
the formula... [tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse
we are given two legs so we plug in a and b and solve for c
[tex]7^2+24^2=c^2\\7^2=49\\24^2=576\\576+49=625\\625=c^2\\\sqrt{c^2} =c\\\sqrt{625} =25\\c=25[/tex]
so we can conclude that the missing side length ( or z) equals 25
now to solve for the angles
Trigonometry
We can solve for y using sin
sin = opposite side divided by the hypotenuse
the opposite of y is 7 and the hypotenuse is 25
so we set up an equation [tex]sin(y)=\frac{7}{25}[/tex]
now we solve for y
[tex]\frac{7}{28} =.28\\arcsin(y)=y\\arcsin(.28)=16.26020471[/tex]
then we round to the nearest hundredth
so we can conclude that angle labeled y = 16.26
basic geometry
Remember all of the angles in a triangle add up to equal 180 so we can find x by subtract the known angles from 180
180 - 90 - 16.26 = 73.74 so we can conclude that x = 73.74
