Answer:
Angle 1: 150°
Angle 2: 30°
Angle 3: 150°
Step-by-step explanation:
1 is 150° because a line is 180° total, and 180-30= 150°
2 is 30° because they are the same angle just reflected across the y-axis.
3 is 150° because they are the same angle as 1 just reflected across the x-axis.
s = 1800°
To find the sum of interior angles in a polygon you can use the following equation

Answer:
334 in^2.
Step-by-step explanation:
The surface area = area of the top prism + area of the bottom - 2 * area of the base of the top smaller prism
= 2(5*3 + 5*3 + 3*3) + 2(9*7 + 9*5 + 7*5) - 2* 3*5
= 2* 39 + 2*143 - 30
= 334
