SinA=8/17, so arcsin(8/17) is your angle of A (around 49 degrees). 90-A is your angle for B
8/21 is the answer to the question
We will use tangent here as we are finding the opposite with the adjacent given.
So we can simply just put this into a calculator:
tan(68°) × 7 cm = AC
tan(68°) × 7 cm = 17.3 cm
The answer is X = 11 - 3. This is because to calculate the original value of how many books Isabella had, you have to take away the amount purchased from the overall total amount. Therefore, the equation is x = 11-3
Answer:
they are both equal 12x+8 is equal to 12x+24
Step-by-step explanation:
distribute:
3 x 4x = 12x 3 x 4 = 24
