Answer:
C 126 in²
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h
b1 is the bottom base length = 12 inches
b2 is the top base length = (2+12+2) = 16 inches
h = height = 9 inches
A = 1/2 (12+16) *9
A = 1/2(28)(9)
A =126 in^2
Answer:
The value of x = 27
Step-by-step explanation:
Given:
48x² : 64x⁴ ::: x : 36x²
Find:
The value of x
Computation:
(a)(d) = (b)(c)
(48x²)(36x²) = (64x⁴)(x)
(1,728x⁴) = (64x⁵)
x = 27
The value of x = 27
Answer:
I think its C
Step-by-step explanation:
Answer: 75°
Step-by-step explanation:
Using the Base Angles Theorem, we can conclude that <ABC and <ACB are congruent. The angles of a triangle add up to 180 degrees so we can write this equation to solve for x:
x + 5 + 3x + 3x = 180
simplify
7x + 5 = 180
subtract 5 from both sides
7x = 175
divide each side by 7
x = 25
plug 25 in for x to find the angle measure
3(25) = 75
