Answer:
it is the first one
Step-by-step explanation:
Explanation:
To do long division, follow the method pattern "DMS down".
D for divide.
M for multiply.
S for subtract.
Down is to bring down.
Use an example:
52 ÷ 2?
Divide 2 by the first digit of 52.
2 Whenever you divide, put the answer at the top.

0 You stop when you get to 0. If you ran out of digits to bring down, write this as a remainder.
Here in this question, we are to solve for x and get the measure of Angle A
Mathematically,
∠A = ∠B
The reason for this is because both are corresponding angles and corresponding angles are equal.
Since they are equal in value, we can equate the given expressions for each of the two angles
Thus;
7x + 40 = 3x + 112
Let us collect like terms
7x-3x = 112 - 40
4x = 72
x = 72/4
x = 18
But the question asks to get the value of ∠A
From the questionn, we are told that ∠A = 7x + 40
To get the value of ∠A, we need to substitute x
∠A = 7(18) + 40
∠A = 126 + 40
∠A = 166
∠A = 166 and x = 18
