Answer:I hope this helps c=60.26
Step-by-step explanation:
The area is 289
Answer:
Okay so this is simple addition, once you know how to do it.
The interior angles of a triangle should always add up to 180 Degrees.
Now that you know this, all you have to do is add the numbers together and see which ones add up to 180 degrees.
A. - 90+42+58=190
B. - 60+60+60=180
C. - 100+48+42=190
D. - 31+75+70=176
Out of these choices the only one that adds up to 180 is B. So your answer would be B.

Answer:
m∠M = 79°
m∠N = 66°
Step-by-step explanation:
∠MPN is supplementary to ∠MPQ, so m∠MPN = 35
The sum of the measures of a triangle is 180.
So, m∠M + m∠N + m∠MPN = 180
5y + 4 + 4y + 6 + 35 = 180
9y + 45 = 180
9y = 135
y = 15
m∠M = 5y + 4 = 5(15) + 4 = 75 + 4 = 79
m∠N = 4y + 6 = 4(15) + 6 = 66
Another way to do this problem, which is easier, is to know that an exterior angle of a triangle is equal to the sum of the two remote interior angles.
That means 5y + 4 + 4y + 6 = 145
9y + 10 = 145
9y = 135
y = 15
From knowing the value of y you can now find the measures of angles M and N
