Answer:
x = 3
Step-by-step explanation:
A parallelogram must have two pairs of parallel sides.
For this to be true, the alternate exterior angles of the diagonal must be congruent.
Hence the equation,
<u>10x + 4 = 13x - 5</u>
Simplify.
<u>9 = 3x</u>
<u>x = 3</u>
Answer:
larger angle: 54°
Step-by-step explanation:
90 / (3 + 2) = 18
larger angle: 13 x 3 = 54°
check: smaller angle: 18 x 2 = 36°
54 + 36 = 90°
