Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
First we will establish the equations which we will be using as displayed below:
Equation No. 1 -
A + B = 90°
Equation No. 1 -
A = 2B + 12
To begin with, let's make ( A ) the subject in the first equation as displayed below:
Equation No. 1 -
A + B = 90
A = 90 - B
Next we will substitute the value of ( A ) from the first equation into the second equation and solve for ( B ) as displayed below:
Equation No. 2 -
A = 2B + 12
( 90 - B ) = 2B + 12
- B - 2B = 12 - 90
- 3B = - 78
B = - 78 / - 3
B = 26°
Then we will substitute the value of ( B ) from the second equation into the first equation to solve for ( A ) as displayed below:
A = 90 - B
A = 90 - ( 26 )
A = 64°
ANSWER:
Therefore, the answer is:
A = 64°
B = 26°

Step-by-step explanation:
It's asking to see how far it will go in 6 seconds, and it's travelling downward.
Answer:
8 * 17 = 136
39 * 36 = 1404
1482 + 136 = 1540
Step-by-step explanation:
Answer:
Step-by-step explanation:
3n+15=75
three times a number is 3n. +15 is 15 more.
3n+15=75 subtract 15 from both sides to get the 3n alone
3n=60 divide by 3 to get the n by itself
n=20
