we know that
The sum of all interior angles in the polygon is equal to the formula

where
n is the number of sides of the polygon
In this problem we have

substitute the value in the formula

<u>Find the value of x</u>

therefore
<u>the answer is</u>
the measure of x is 
Answer:
Step-by-step explanation:
question no 3
In complementary angles , sum of two angles is 90 degree. so here,
angle A + angle B = 90 degree
angle A is given i.e 11 degree . substitute the value of A
11 degree + angle B= 90 degree
angle B = (90 -11) degree
angle B = 79 degree
question no 4
In supplementary angles , sum of two angles is 180 degree so here,
angle A + angle B = 180 degree
angle A is given i.e 149 degree . substitute the value of angle A
149 degree + angle B = 180 degree
angle B = (180 - 149) degree
angle B = 31 degree

Answer:it’s d
Step-by-step explanation:
The parabola (u sharp thing lol) passes the horizontal (x axis) and it touches the horizontal line twice... this is always. If you look closely it touches 1, -5 ( the negative comes from being to the left side) and since this is your horizontal line both these number go first (1) (-5) then you just include the 0s because the y intercept is always like that majority of times but also bc it’s not touching that lines (vertical line heheh) hope that makes sense.
