Answer:
43,51, 86
Step-by-step explanation:
The sum of the angles of a triangle are 180
x+ x+8+2x = 180
Combine like terms
4x+8 = 180
Subtract 8 from each side
4x+8-8= 180-8
4x= 172
Divide each side by 4
4x/4 = 172/4
x=43
x+8 = 43+8 = 51
2x = 43*2 = 86
The three numbers are 93,94,95

Simple :)
Area of shaded part = are of 1/4 circle - area of both triangles.
Are of circle = pie r^2 so 100x3.14 = 314 cm2.
Area of triangle AOB= area of triangleDOE = bh/2= 5x10/2= 25 each
However, the traingles share a common area which is quad DOB(I)
Lets take traingle AOE, whose are is bh/2=10x10/2=50cm2.
50-area of triangle A(I)E= 50-(
The area of the given trapezoid is 38 in².
<h3>What is a
trapezoid?</h3>
A trapezoid is a quadrilateral (has four sides and four angles) with a single pair of parallel sides. The area (A) of a trapezoid is given by:
A = (1/2) * (a + b) * h
Where a, b are the parallel sides and h is the height of the trapezoid.
Given that a = 8, b = 11, h = 4, hence:
A = (1/2) * (8 + 11) * 4 = 38 in²
The area of the given trapezoid is 38 in².
