BC is already written in the question stem as being 11.4
Answer:
The measure of angle A is: m∠A = 96
Therefore, option A is true.
Step-by-step explanation:
Given
m∠C = 3x
m∠D = x+52
We know that the opposite angles of a parallelogram are also equal.
Determining m∠A
It is clear that A is the opposite angle of C.
i.e.
m∠A = m∠C
as m∠C = 3x
so m∠A = 3x
Determining m∠B
It is also clear that B is the opposite angle of D.
i.e.
m∠B = m∠D
as m∠D = x+52
so m∠B = x+52
We know that the sum of the angles of a parallelogram is 360°.
so
m∠A + m∠B + m∠C + m∠D = 360°
3x + (x+52) + 3x + (x+52) = 360°
Group like terms
Subtract 104 on both sides
Simplify
Divide both sides by 8
Simplify
Thus,
The measure of the angle A is:
m∠A = 3x
substitute x = 32
m∠A = 3(32)
m∠A = 96
Hence, the measure of angle A is: m∠A = 96
Therefore, option A is true.

Step-by-step explanation:
the steps how i got it and the picture has the ans
(hope this helps can i plz have brainlist :D hehe)
To answer the problem, we must identify the terms first. Our minuend is 13a - 5 and our subtrahend is 16a + 3.
minuend - subtrahend = difference
(13a - 5) - (16a + 3) = difference
<em> difference = -3a - 8</em>
