Answer:
C
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
The exterior angle adjacent to 93° = 180° - 93° = 87°
Sum the exterior angles and equate to 360
78 + x + 52 + 87 + x + 3 = 360 ← simplify left side
2x + 220 = 360 ( subtract 220 from both sides )
2x = 140 ( divide both sides by 2 )
x = 70 → C
x = -1
Given:
Solve for x, When:
Step by step:
1 is D 10,8
2 is B 10, 3
in steps
base width: 1/2 x 5 = 2.5
base length: 1/2 x 4 = 2
height: 1/2 x 3 = 1.5
Volume: lwh = 2.5 x 2 x 1.5 = 7.5 in³
1/25
f(x)=5^x
Let x = -2
f(-2)=5^-2
We know that a^-b = 1/a^b
= 1/5^2
= 1/25
