Answer:
Step-by-step explanation:
angle A = angle B (because they are alternate exterior angles)
8x+6=4x+38
8x-4x=38-6
4x=32
x=32/4
x=8
For angle A
8x+6
8*8+6
64+6
70
For angle B
4x+38
4*8+38
32+38
70
Answer: 832 cm².
Step-by-step explanation:
1. To calculate the lateral area of the prism by using the net you must:
- Calculate the perimeter of the base:

Where l is the lenght and w is the width:

Then:

- Now you must multiply the perimeter by the height. The height is 13 cm.
Then, the lateral surface area is:

Answer:
C
Step-by-step explanation:
C, the answer is exponential function
The base should be 4.
Area=1/2* b *h
4*7=28/2=14.
