Answer:
Correct answer: m∠A = 52°
Step-by-step explanation:
Given:
m∠A = 9 x - 2 = ?
m∠B = 16 x
m∠C = 5 x + 2
The sum of the inner angles in a triangle is 180 degrees
m∠A + m∠B + m∠C = 180°
9 x - 2 + 16 x + 5 x + 2 = 180
30 · x = 180
x = 180 / 30 = 6°
x =6°
m∠A = 9 x - 2 = 9 · 6 - 2 = 54 - 2 = 52°
m∠A = 52°

Answer: Amount of change : $30
percent increase : 200%
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Wholesale price: $15
</em>
- <em>Retail price: $45
</em>
To obtain the amount of change we have to subtract the wholesale price to the retail price:
Mathematically speaking:
45 -15 = $30
For the percent increase, the amount of change (30) is some percent of the original price (15). So:
30 / 15 =2 (decimal form)
If we multiply it by 100, the percentage is:
200%
Answer:
135°
Step-by-step explanation:
seg AB=seg OB
tan ∠AOB = 1
∠AOB = 45°
∠AOC = 135°
