Answer:
[tex]\huge\boxed{\text{(A)}\ 96 \textdegree}[/tex]
Step-by-step explanation:
A parallelogram has two pairs of identical angles.
The identical angles will be directly opposite from each other.
This means that:
- Angle C = Angle A
- Angle D = Angle B
Therefore, we can say that Angle A is 3x degrees and Angle B is x+52 degrees.
It's also important to note that all angles in a quadrilateral add up to 360°.
Since we know the measure of each angle, we can add up the expressions for each and find x.
[tex]3x + 3x + (x+52) + (x+52) = 360[/tex]
Let's simplify this equation.
- [tex]6x+(x+52)+(x+52)=360[/tex]
- [tex]8x+104=360[/tex]
Now that we know the value of x, let's use it to find the measure of Angle A.
We already proved earlier that Angle C is equivalent to Angle A. Since we know the expression for Angle C (3x) it'll be the same for angle A.
[tex]3(32)=96[/tex]
So A is 96°
Hope this helped!
