Whats the surface area of this shape?

168 square units

Step-by-step explanation:

From left to right, top to bottom

1. 5 x 10 = 50

2. 5 x 8 = 40

3. 5 x 6 = 30

For the triangles since there is 2 of them and there the same we play it like there is 1 square

4 & 5. 8 x 6 = 48

Now add all them

50 + 40 + 30 + 48

50 + 40 = 90

30 + 48 = 78

90 + 78 = 168

168 square units

Step-by-step explanation:

5*10 = 50 (left rectangle)

8*6 = 48 (top and bottom triangles, not dividing by 2 as there is two of that exact shape)

5*8 = 40 (middle rectangle)

6*5 = 30 (right rectangle)

Add them all up

50+48+40+30 = 168.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
