Answer:
Yes, is a right triangle
Step-by-step explanation:
To know if you can build a right triangle with those sides we have to make the following equality
h² = l1² + l2²
The hypotenuse is always the longest side so it should be 39
we check the equality of the equation
39² = 15² + 36²
1521 = 225 + 1296
1521 = 1521
Equality was fulfilled so it is a right triangle
 
        
             
        
        
        
The given angles are known as alternate interior angles.
For line L and M to be parallel, the two given angles must be the same.
 Set them to equal each other and solve for X.
7x - 7 = 4x +14
Add 7 to each side:
7x = 4x +21
Subtract 4x from each side"
3x = 21
Divide both sides by 3:
X = 21 / 3
X = 7

Step-by-step explanation:
116 + 2b = 180
2b = 64
b = 32
 
        
                    
             
        
        
        
Answer:
43°
Step-by-step explanation:
angle 1 and Angle 2 are corresponding angles. app they are equal. 
73-2x = 88-3x
x = 15
angle 1 = 73-(2*15) = 43
angle 2 = 88-(3*15) = 43
