Answer:
Yes, it is a right triangle.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is the hypotenuse so c^2 would be 90.
72^2+54^2=90^2
72 and 54 can be either a or b.
Solve for all exponents: 5184+2916=8100.
That equation is true, so the triangle is a right triangle.
The first one is BC
The second one is AB
Answer:
20
Step-by-step explanation:
8 = 40%
4 = 20 %
8 + 8 + 4 = 20
20 students = 100%
4(3n+7)=16
12n+28=16
12n=-12
n=-1
Answer:
-4, x, |-1.5| , -x, |5|, |6|
Step-by-step explanation:
X = -2
-X = 2
|-1.5| = 1.5
|5| = 5
|6| = 6
