Answer:
B. <1 = 35, m<2 = 30
Step-by-step explanation:
To figure out m<1 I first need to figure out the other missing angle. A straight line is a 180 degree angle. Taking that information you can do 180 - 115. This means that the missing angle is 65 degrees. The interior angles of triangles always add up to 180. 
80 + 65 = 145
180 - 145 = 35
<1 = 35
Repeat with the other side. 
85 + 65 = 150
180 - 150 = 30
<2 = 30
Hope this helps!

whether you have the money to lend her
whether she offers you some collateral
whether she is creditworthy
whether she can repay the loan within a period that suits you
whether she offers to pay interest
 
        
             
        
        
        
This formula only applies if the track is circular.  If it is, then we write the equation:
2*r*pi=400
Dividing by 2pi, we see that:
r=200/pi
This is approximately 63.66.
        
             
        
        
        
P = a + b + c
P = 72
a = x
b = x + 2
c = x + 4
72 = x + x + 2 + x + 4
72 = 3x + 6
72 - 6 = 3x
66 = 3x
66/3 = x
22 = x
x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26
the sides of ur triangle are : 22,24,26 <==
