Answer:
88.67
Step-by-step explanation:
We know that a triangle's angles adds up to 180 degrees.We can make a equation: x+15+32+2x=180
x=44.3
Don't forget to times 2 to get L
Then L equals 88.67.
Answer:
15 sides
Step-by-step explanation:
Interior angle = {n - 2}{180/n}
156 = {n - 2}{180/n}
Cross multiply
156n = {n - 2}180
156n = 180n - 360
180n - 156n = 360
24n = 360
n = 369/24
n = 15

Answer:
D. 63 degrees
Step-by-step explanation:
For the first answer
Cos B = 0.45
tan60 = √3
= 60° = arctan √3
Cos B = 0.45
B = 63°
Thus B = arc cos 0.45 = 63°
