Answer:
Step-by-step explanation:
Back
Area = L * W
L = 20
W = 8
Area = 20 * 8
Area = 160
2 Triangles
Area = 1/2 one smaller leg*other smaller leg
one smaller leg = 8
The other one = 15
Area = 1/2 8 * 15 = 60
But there are 2 of them 2 * 60 = 120
Base
L = 20
W = 15
Area = L * W
Area = 20*15 = 300
Front (slanted) Face
L = 20
W = 17
Area = L * W
Area = 20*17 <u> 340</u>
Total 920
Answer: 
Step-by-step explanation:
Using the same-side interior angles theorem, 
.
Using the alternate interior angles theorem, 
=> 4(7)–2(7+a)=8
<h3>=>28–14
<em>–</em>2a=8</h3><h3>=>14–2a=8</h3><h3>=>-2a=8–14</h3><h3>=>
<em>-</em>2a=-6</h3><h3>
<em>=>a=3</em></h3>
