9) find the value of the exterior angle in the diagram provided.

150 degree. (D)

Step-by-step explanation:

From the diagram provided above,

In the theorem of a triangle, the sum of the opposite interior angle of a triangle equals to the exterior angle of that triangle.

Therefore, the interior opposite angle of this triangles are

(x + 40) degree and (3x + 10) while the exterior angle = 6x degree.

Base on the theorem above

x + 40 + 3x + 10 = 6x

then solve for x

4x + 50 = 6x

6x - 4x = 50

2x        = 50

divide by 2

x  = 50/2

x = 25.

Therefore , the exterior angle in the diagram = 6 x 25

                                                                          =  600/4

                                                                          = 150 degree.

The value of the exterior angle is 150 degree

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

brainliest

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
