Answer:
A)18in.
Step-by-step explanation:
Given,
A trapezoid Area= 216 sq
The length of its longer base=2x
The length of its shorter base= x
Height of Trapezoid = 8in
Area of Trapezoid= 1/2h(a+b)
216=1/2 x 8(2x+x)
216=4(2x+x)
216/4=3x
54=3x
54/3=x
18=x
Length of shorter base=18
Length of longer base=2x18=36
Hence, the length of the shorter base is 18in
Option A) is correct
Answer: y-2=1/4(x-1)
Step-by-step explanation:
The formula for point-slope is y-y₁=m(x-x₁). Since we are given the slope m, we can fill that in. We are also given the point (x₁,y₁). We can also fill that in.
y-2=1/4(x-1)
Answer:
(C)Determine the principal square root of both sides of the equation.
Step-by-step explanation:
Given: Isosceles right triangle XYZ (45°–45°–90° triangle)
To Prove: In a 45°–45°–90° triangle, the hypotenuse is times the length of each leg.
Proof:
Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem,
Since a=b in an isosceles triangle:
Therefore, the next step is to Determine the principal square root of both sides of the equation.
