Answer:

x = 50

Step-by-step explanation:

Since the two angles are supplementary, add them together and set them equal to 180 degrees

2x + 2x - 20 = 180          Combine like terms

4x - 20 = 180

   + 20   + 20                 Add 20 to both sides

4x = 200                        Divide both sides by 4

x = 50

At right angles.)<br> 4 m<br> 4 m<br> 2 m<br> 2 m<br> 7 m<br> 2<br> 3 m<br> 7 m<br> 11 m
Arisa [49]

Answer:

71

Step-by-step explanation:

Area of fig 1 = 1 x b = 7 x 4 = 28

Area of fig 2 = l x b = (7-2) x 3 = 5 x 3 = 15

Area of fig 1 = 1 x b = 7 x 4 = 28 (same as ig 1)

Area of whole fig = fig 1 + fig 2 + fig 3 = 28+15+28 = 71

I hope im right !!
