Answer:
1. The measure of ∠WOV is 60°. You would use complementary angles that are adjacent (∠WOV, and ∠XOW)
2. The measure of ∠YOZ is 60°. You would use the vertical angles that are non-adjacent (∠WOV, and ∠YOZ). These two angles are congruent so they would have the same measure. These angles combined also create supplementary angles
3. Another way to find the measure of ∠YOZ would be to make/write an equation and solve for x. For example, (3x+30)°=60°. x would equal 10 because 10x3=30+30=60°
Step-by-step explanation:
1. Since a complementary angle would equal 90°, simply subtract 30° from 90° resulting in 60°.
2. Because vertical angles are congruent and (∠WOV, and ∠YOZ) are a pair of them, they equal the same as each other so they're both 60°.
3. You can make any equation with x included as long as it equals 60° mine was just an example you can make your own like 10x+10=60 or 4x+20=60. Also to create your equation you also need to use the angle fact of the vertical angles
Around 15.16666. I hope this helps!
Answer:

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- percent
- percentage words problem
- PEMDAS
<h3>given:</h3>
- population:2500
- decreasing rate:3%
<h3>to find:</h3>
- the population after 11 years
<h3>let's solve:</h3>
according to the question
population decreases in 1 year

population will decrease in 11 years
so the population of the town after 11 years will be
2500-825
<h2>1675</h2>
Answer:
Pythagorean Theorem and Sine
Step-by-step explanation:
you could use pythagorean theorem to find the 3rd side, then use inverse sine of c.
Using the equation a2 + b2 = c2
Subtract 13squared from 5squared
169-25
then take the square root of the answer- which is 12
then do the inverse of sine
that should give you the missing angle
