Answer:
Surface area:
Step-by-step explanation:
(Imagine there's line separating the rectangle and square)
<u>Rectangle</u>
l × w × h
3 cm × 13 cm × 3 cm
117 cm^3
<u>Square</u>
5 cm × 2 cm × 3 cm
30 cm^3
<u>Total Area</u>
117 cm^3 × 30 cm^3
3,510 cm^3
<em>Hope this is enough of an "explanation." Glad I could help though!</em>
x=20°
(6x+2)° and (5x+22)° are vertically opposite angles, hence VOA angles are equal so
(6x+2)°=(5x+22)°
6x°+2°=5x°+22°.... collect the like terms
6x°-5x°=22°-2°
x°=20°
Expand the brackets.
Multiply.
