Answer:
156°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 15 , then
sum = 180° × 13 = 2340°
interior angle = 
= 
= 156°
Answer:
Substitute the numbers below x by x in the equation given in the middle of the table and that will be the answer for y.
Step-by-step explanation:
For example, x= -1
y= x + 6
y= -1 + 6
y= 5
Answer:
The answer is D. 59.0
Step-by-step explanation:
6 x 10 = 60.
60 is close to 59.0
Answer: 2
Step-by-step explanation:
Answer:
Explanation:
1) The two parallel sides of different legths 1\frac{3}{4}143 and 1\frac{1}{4}141 constitute the bases of a trapezoid.
2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.
An isosceles trapezoid is truncated isosceles triangle.
The definition of trapezoid is a quadrilateral with at least two parallel sides.
The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.
