<h2>Hello!</h2>
The answers are:
Question 7:
154.29°
Question 8:
Yes, because the opposite sides are congruent.
<h2>Why?</h2>For question 7:
We know that the sum of all interior angles of any polygon is determined by the following formula:
Therefore the sum of all interior angles of a 14-gon is equal to 2160°, so, the measure of each interior angle is given by the following calculation:
Each interior angle is equal to:
For question 8:
We know that a quadrilateral is a parallelogram when the opposite sides are parallel or congruent.
From the statement we know that:
BE≅ED
and
AE≅EC
So, we can assume that the triangles formed by the sides BE and AE, and the sides EC and ED, are also congruent, meaning that the opposite sides BA and CD are congruent, so, the quadrilateral is a parallelogram.
Have a nice day!
Answer:
Step-by-step explanation:
The y-intercept is where x is 0 (0,y)
The x-intercept is where y is 0 (x,0)
Insert 0 as the value for x to find the corresponding y value:
Simplify multiplication:
Isolate the variable. Divide both sides by 4:
Make the variable positive. Multiply both sides by -1:
The y-intercept is at .
Insert 0 as the value for y to determine the value of x:
Simplify multiplication:
Isolate x. Divide both sides by 5:
Multiply both sides by -1:
The x-intercept is at .
