Answer:
x = 4/9
Step-by-step explanation:
7(6x + 1) = 3(9 - x)
First, distribute the 7 and the 3 across the parentheses.
42x + 7 = 27 - 3x
Now, combine the variables. (Add 3x)
45x + 7 = 27
Now, combine the constants. (Subtract 7)
45x = 20
Now, isolate the x. (Divide by 45)
x = 20/45
Simplify.
x = 4/9
Answer:
x ≈ 35.1°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = 
= 
, then
x = 
( ) ≈ 35.1° ( to the nearest tenth )

Answer:
mA = 69 degrees
Step-by-step explanation:
A complementary angle has a measure of 90 degrees.
(2x + 27) + (2x - 21) = 90
Simplify
4x + 6 = 90
-6
4x = 84
/4
x = 21
mA: 2(21) + 27 = 69
