You are trying to find the side between the right angle and the degree (This is known as the adjacent)
You are given degree 42
You also given the longest side of 19 (This is known as the hypothenuse)
Cosine: adjacent/hypothenuse
Cos42 = x/19
0.7431448255 = x/19
x = 19 * 0.7431448255
x = 14.11975168, round to tenth
Solution: x = 14.1
Answer:
he has to sell 150!
Step-by-step explanation:
1500 divided by 10% = 150!
3x - 12
Triple a number would be 3x instead of x cubed as it is not asking for a number multiplied by itself three times.
-12 is the second half as since you don’t know whether or not the variable will be larger or smaller than the constant, it is safer to put it on the other half.
Thus, this equation fills in the worded format.
Hope this helps!
