Answer:
<h2>The answer is 114°</h2>
Step-by-step explanation:
Let the exterior angle be B
To find the exterior angle we must first find the value of x using one the angle property of triangles which is
the sum of any two interior angles in the triangle is equal to an exterior angle of the triangle.
To find x, add up the two given interior angles and equate to the exterior angle
We have
3x + 6 = 24 + 2x + 18
3x + 6 = 2x + 42
3x - 2x = 42 - 6
x = 36
From the question
B = (3x + 6)°
B = 3(36) + 6 = 108 + 6
We have the final answer as
<h3>114°</h3>

Answer:
let x=one number =
x-2= another number
x²- (x-2)²=20
x²-x²-4x+4=20
-4x=20-4
-4x=16
x=16/-4
x=-4
one number is -4
x-2
-4-2
=-6
the another number is -6
Width = w
Length = 2w + 5/2
Perimeter = 2(Length + Width)
Perimeter = 2( w + 2w + 5/2)
Perimeter = 2(3w + 5/2)
Perimeter = 6w + 5
