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°

Answer:
i cant see it
Step-by-step explanation:
So we know each inch is 3 feet.
1:3.
13:?
So we multiply 13 by 3 to get the answer!
13:39
or 39 feet!
I hope this helped! :))
Step-by-step explanation:
2x2 + 10 - 3x - 3 + 3
Solving like terms
2x2 - 3x + 10
Option B is the correct answer
It is just asking for you to convert 3/4 in 84ths. This means it wants the denominator to be 84. So multiply both the top and bottom by what gets you 84. In this case, multiply both by 21. So 3/4•(21/21)=63/84
