For the first one, the angles are vertical so they have the same measurement. Set them equal.

110 = 6x + 2; subtract 2 from both sides

108 = 6x; divide both sides by 6

18 = x

For the second one, there are a total of 180° in a triangle so set them equal to 180.

2x + 16 + 42 = 180

2x + 58 = 180; subtract 58 from both sides

2x = 122; divide both sides by 2

x = 61

I hope this helps!

Answer for Problem 2:

x=61 degrees

Step-by-step explanation:

I'm not completely sure of problem 1, but I know what problem 2 is.

Tip: triangles always add up to 180 degrees.

1. 16+42= 58

2. 180-58= 122

3. 122 divided by 2= 61 degrees

ANSWER: x=61 degrees.

Answer:

$\frac{1}{81}$

Step-by-step explanation:

Using the rule of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$ , then

$3^{-4}$ = $\frac{1}{3^{4} }$ = $\frac{1}{81}$
