Answer:
14) x = 0°
16 x = 2°
Step-by-step explanation:
14)
BJK = 146+2x
IJK = 172
IJB = 2x + 26
IJK = IJB + BJK
172 = 146 + 2x + 2x + 26
172 = 146 + 26 + 4x
172 = 172 + 4x
0 = 4x
x = 0°
16)
LMN = 135
LMV = -1 + 45x
VMN = 23x
LMN = LMV + VMN
135 = -1 + 45x + 23x
135 = -1 + 68x
136 = 68x
x = 2°

Well, if you're rounding to 1 significant figure, which you'll mostly be asked to do,
You look and see which number is the first one which isn't a zero. The most significant. In this example, the 8. You then need to look at the second number, it's a zero. It has no value and doesn't do anything to the 8. The number after that gets rounded down to a zero, it's too far away to effect the 8, and even if it could it's too low.
The answer is 8.
(Sorry if my answer was a bit complicated...)
Substitute the value of the variable into the equation and simplify.
