Question

Help me plz:(


It’s just 22-24

Answer 1

D. ("24.")

Explanation:

it is D

Answer 2

1) 5.9

2) 8.1

3) 54

Explanation:

A is opposite, so we have sine 36=a/10

sine 36(10)=a

a=5.9

B is adjacent, so we have cosine 36=b/10

cosine 36(20)=b

b=8.1

Angles of a triangle add to 180

we have a angle of 36 and a right angle which is 90

36+90=126

180-126=54
