<u>Answer</u>:
A. ![\frac{21}{4} \pi\ \space\ in](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B4%7D%20%5Cpi%5C%20%5Cspace%5C%20in)
<u>Step-by-step explanation:</u>
The formula for arc length is:
arc length = rθ
where:
r is the radius = 7 in
θ is the central angle in radians = 135 ×
= 3/4 π
Substituting these values into the formula:
arc length = 7 in × 3/4 π
= ![\frac{21}{4} \pi\ \space\ in](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B4%7D%20%5Cpi%5C%20%5Cspace%5C%20in)
The underlined digit equals 20.
Answer:
<u><em>85 degrees</em></u>
Step-by-step explanation:
A triangle's angles must add up to 180 degrees.
50 + 45 = 95
180 - 95 = 85
x = 85
Answer:
y= -2/3x + 8/3
