Answer: 12.9

Step-by-step explanation:

We first find the surface area of every single triangle. The area of a triangle and be shown as b*h/2, where b is base and h is height.

2*3/2 = 3

multiply by 3 since there are three of these sides.

3 * 3 = 9
find the area of our base

3*2.6/2 = 3.9

Add them all up

3.9 + 9 = 12.9

Answer:

angle DEG=47+30(sum of two interior opposite angle is equal to the exterior angle formed)

DEG=77 degree

DEF+47+30=180(being sum of interior angle of a triangle)

DEF+77=180

DEF=180-77

DEF=103 degree

measure of each angle is 60 degree

Find the value of x...X=?
Romashka [77]

Answer:

The value of  x° = 134°

Step-by-step explanation:

Given the angles of a quadrilateral

  • 100°
  • 51°
  • 75°
  • x°

We know that the sum of interior angles in a quadrilateral is 360°.

so

100° + 51° + 75° + x° = 360°

226° + x° = 360°

subtracting 226° from both sides

226° + x° - 226°  = 360° - 226°

x° = 134°

Therefore, the value of  x° = 134°

VERIFICATION:

100° + 51° + 75° + 134° = 360°

360°= 360°
