Use the equation A=(1/2)bh
Replace b with 7
Replace h with 12
A=(1/2)(7)(12)
A=(1/2)(84)
A=42
Two pairs of corresponding angles are congruent, so the triangles are similar.
The correct option is (A).
<h3> What is similarity in triangles?</h3>
Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
As, the measurement of two angles are equal.
So, the angles are congruent.
Hence, by AA criteria the triangles are similar.

You would need to substitute a number for y. I would probably put 0 for y which would then give you x.
y = 0
x = 1
Then you can easily graph the point. :)
Answer:
6.1° and 83.9°
Step-by-step explanation:
Complementary angles sum 90°
a+b = 90°
a = b - 77.8
then:
(b - 77.8) + b = 90
2b - 77.8 = 90
2b = 90 + 77.8
2b = 167.8
b = 167.8/2
b = 83.9°
a = b - 77.8
a = 83.9 - 77.8
a = 6.1°
