How can recycling possibly take away energy

Producing new materials from recycled products uses significantly less energy than creating a whole new product from raw materials. When you recycle your waste it saves a lot of energy because it cuts back on the mining, extracting, processing, and shipping of raw materials that make our everyday products.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
