half of the triangle is a right angle triangle, so we use the phythagoras theorem and multipy our answer by 2
Answer:
i think its a <em>knockoff</em>
Step-by-step explanation:
The answer is D. The answer is D because you just keep multiplying each number by the same number.
6 • 8 = 48
7 • 8 = 56
<u>Answer:</u>
x = 14° || each angle has 108°
<u>explanation:</u>
first we need to find the total interior angle of this shape:
formula: ( n - 2 ) * 180 ..............where n is the number of sides
( 5 -2 ) * 180
540°
if all sides in the shape are equal, they must have same angle of 9x -18
5 ( 9x -18 ) = 540°
9x -18° = 108°
9x = 108° + 18°
9x = 126°
x = 14°
So each angle has: 9x - 18
9(14) - 18
108°
