Answer:
5. m26+m27+m28= m81
Step-by-step explanation:
because 26+27 =53 and you just plug in m
and 28+53 = 81
Answer:

Step-by-step explanation:
Given:
Area of the square = 49 in²
Required
Determine the perimeter of the one of the congruent triangles
First, we'll determine the length of the square;

Substitute 49 for Area


Take Square root of both sides


<em>When the square is divided into two equal triangles through the diameter;</em>
<em>2 sides of the square remains and the diagonal of the square forms the hypotenuse of the triangle;</em>
Calculating the diagonal, we have;
-- Pythagoras Theorem


Take square root of both sides



The perimeter of one of the triangles is the sum of the 2 Lengths and the Hypotenuse



Answer:
x = 45
Step-by-step explanation:
x + 135 = 180 {Linear pair}
x = 180 - 135 {Subtract 135 from both sides}
x = 45
Answer: 160 degrees
Step-by-step explanation:
(18-2)180 = 2880
2880/18 = 160
