Answer:
Area of green trapezoid would be:
(length of two parallel sides × h) ÷ 2
( 5cm x 2cm) ÷ 2
= 5 square centimetres
Area of the orange trapezoid would be:
(length of two parallel sides x h) ÷ 2
(10.5 cm × 3) ÷ 2
( 31. 5) ÷ 2
(15. 75 square centimetres
NOTE: h represents height
Answer:
x = -8°
Step-by-step explanation:
Angle 2
Since the triangle is isosceles, Angle 2 is the same as the missing angle
So angle 2 would be:
180 - 34 = 2(angle 2)
So 146 = 2(x + 81)
146 = 2x + 162
146 - 2x = 162
-2x = 16
x = -8
Check
146 = 2(-8+81)
146 = 2(73)
146 = 146
Correct!
