Answer:
A = 37 degrees ; B = 82 degrees
Step-by-step explanation:
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees

Answer:
A. 21.2
Step-by-step explanation:
Using trigonomteric ratio, Cosine
Cosine B = a/c
But; c = 24
B = 62
Cos 62 = a/24
a = 24 × cos 62
= 11.26
Using Pythagoras theorem we can get b;
since; a² + b² = c²
b² = 24² - 11.26²
= 449
b = √449
= 21.19
≈ 21.2
