Answer:
152°
Step-by-step explanation:
If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.
The measure of each angle in the other congruent pair is 152°.
Y= 2x+5
According to the slope int. formula,
y=mx+b
here, slope, m=2
y int, b =5
so, the equation is y=2x+5
the side x is 15
bottom right angle is 31.61 degrees
other angle is 58.39 degrees
A = hb/2
A = (15)(11) / 2
A = 165/2
A = 82.5 <===
