Answer:
The answer is F: 108
Step-by-step explanation:
144 - 108 = 36
108 ÷ 3 = 36
CB = DA = √3*3+1*1 = √10
CD = BA = √2*2+1*1 = √5
Sum is 2√10 + 2√5 ≈ 10.8. So answer A.
Answer:
I think B
Step-by-step explanation:
Answer:
Hi! The correct answer is x=3!
Step-by-step explanation:
<u><em>~Isolate the variable by dividing each side by factors that don't contain the variable~</em></u>
Supplementary = 180 degrees...
A + B = 180
3x + 12 + 7x + 38 = 180
10x + 50 = 180
10 x = 130
x = 13
To find the A just substitute x in...
3 ( 13) + 12
A = 51
To check substitute the x..
A + B = 180
3(13) + 12 + 7(13) + 38 = 180
51 + 129 = 180
180 = 180
