- 2) then equate the values of given question
- 3) you will find the solution
Answer:
x = 2
Step-by-step explanation:
all the angles in a triangle that are added together will equal 180 degrees
so having known that you will get this equation: \/
2x+5+8x=25
then you solve
8x+2x+5=25
10x+5=25
10x=20
x=2
Answer:
height = 11.5 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A =
h(a + b)
where h is the height and a, b the bases
here a = 21, b = 8 and A = 166.75, hence
h(21 + 8) = 166.75
Multiply both sides by 2 to eliminate the fraction
29h = 333.5 ( divide both sides by 29 )
h = 11.5 in
