Answer:4.375
Step-by-step explanation:
Answer:
D. m∠A=43, m∠B=55, a=20
Step-by-step explanation:
Given:
∆ABC,
m<C = 82°
AB = c = 29
AC = b = 24
Required:
m<A, m<C, and a (BC)
SOLUTION:
Find m<B using the law of sines:








m<B = 55°
Find m<A:
m<A = 180 - (82 + 55) => sum of angles in a triangle.
= 180 - 137
m<A = 43°
Find a using the law of sines:


Cross multiply


(approximated)
Answer:
Answer choice A
Step-by-step explanation:
This is the midpoint of both coordinates.
Add all the angle and =to 180 because all the angle in a triangle add up to 180 then put all numbers on one side and all x terms on the other side then you find x
Answer:
18
Step-by-step explanation:
just multiply
