Divide 25 by two and which is 12.5 then multiply that by 5 and you get you’re answer
        
             
        
        
        
I believe it is 50 degrees 
Explanation:
180-115 = 65 degrees 
Since the base angles of of an isosceles triangle are equal,
Angle C =angle A= 65 degrees
65 times 2 = 130
180-130=50
50 degrees=measure of angle B
Hope this helps
 
        
             
        
        
        
Answer:
(-4,-2)
Step-by-step explanation:
first u should chose a variable to eliminate and i choose Y
y=5/2x+8-y=-1/4x-3
get a common denominator 
5/2= 10/4
-1/4=-1/4
the equation i will change a little because we are subtracting
10/4x+8+1/4x+3
11/4x+11
solve for the remaining variable which is X
subtract 11 on both sides
0-11=11/4x+11-11
-11=11/4x
multiply both sides by 4/11
-11 times 4/11= 11/4x times 4/11
x=-4
then substitute the variable in one of the equations and i choose y=5/2x+8
5/2(-4)+8= y
-20/2+8= y
-10+8=y
y=-2
