Answer: -4
Step-by-step explanation:
2.5x = -10
1. divide -10 by 2.5
2. x = -4
SO you know that triangles add up to 180. A right angle equals 90 so 180-90=90. And an isosceles triangle means that 2 angles are congruent. SO 90/2 = 45. The measure of the 2 acute angles are 45
12/x = 15/8
96 = 15x
x= 6.4 or 32/5
Plug in -3 for x into the equation.
(1/4)^-3
And solve
(1/4)^-3 = 64
Answer:
8 squares
Step-by-step explanation:
Count the squares- 5
then count the triangles- 6
2 triangles is one square- 3
add the triangles and squares
5+3=8
