Answer:
3)
x = 5.3
4)
<A = 22.6°
<B = 67.4°
Step-by-step explanation:
Tan(A) = 5/12
<A = 22.6°
Tan(B) = 12/5
<B = 67.4°
Or you can find <B = 90 - <A) = 90° - 22.6° = 67.4°
3)
tan(24) = x / 12
x = 12 * tan(24)
x = 12 * 0.4452
x = 5.3
1/4 = .25
so .25x = 20
divide
and u get 80
76 divided by 4 is 19. Add a zero and the answer is 190.
Hope this helps you !!
5c+4 is equivalent
Its just simplified.
