Answer:
28
Step-by-step explanation:
a = √8² - 6²
= √64 - 36
= √28
Answer: √28
Solution:
The three squares form a triangle where the hypotenuse is 8 and the right side is divided into 6 and a.
So 8^2 = 6^2 + a^2
(Using the Pythagorean theorem)
64 = 36 + a^2
64 - 36 = a^2
28 = a^2
a = √28

Answer:
B.
Step-by-step explanation:
So you have to find the base of the trapezoid.
12 + 6 + 2 = 20
If I did the math correctly I’d should be -5 or rewritten as -5/1.
I think it’s 28.35
54/100 x 5 = 2.7
54 + 2.7 = 56.7
56.7/100 x 50 = 28.35
56.7 -28.35 = 28.35
