Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.

Move all the logarithms on the left hand side, and all the constants on the other:

Use the rule of logarithms

To rewrite the equation as

Evaluate 2 to the power of each side:

Multiply both sides by 2x:

Answer:
C
Step-by-step explanation:
According to SohCahToa, cosine is adjacent over the hypotenuse.
The adjacent when looking from angle b, is 21.
The hypotenuse of this triangle is 29.
So Cos B=21/29
