If you take 180-90 because of the right angle would be 90° then -15 you will get 75 which will be X
Answer:
Step-by-step explanation:
A = 150°
B = 12°
C = 180 - (150 + 12) = 18°
b = 10 cm
Apply the sine rule:

Plug in the values

Multiply both sides by sin(18)


c = 14.9 cm (nearest tenth)
A) Integers and d) rational numbers
it can't be natural because -13 is <1, can't be whole because it's <0 and it can't be irrational because it's rational (can be expressed as a fraction)
Answer:
x+.8x=27
1.8x=27
x=15
4/5(15)=12
So 15 and 12
