Help, anyone can help me do quetion.​

(a) x =

(b) x =

Step-by-step explanation:

A. sum of angles in a polygon = (n - 2) 180

The polygon given is an irregular pentagon, where n = 5

So that;

sum of angles in a pentagon = (5 - 2) 180

                        = 3 x 180

                        =

Thus,

x + 90 + 76 + 110 + 136 =

x + 412 =

x = - 412

x =

B. The polygon given is an irregular pentagon, where n = 5.

Let the supplementary angle with angle 38 be represented by y,

y + 38 = 180

y = 180 - 38

  =

y =

Let the supplementary angle with x be represented by z, so that;

z + 72 + 120 + 100 + 142 =

z + 434 =

z = - 434

  =

z =

But, x + z =

Then;

x + =

x = -

  =

x =

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction
