Answer:
m<6=77°
Step-by-step explanation:
Because the angles marked 3x+5 and 4x+7 are same side exterior angles, they are supplementary, meaning that 
3x+5°+4x+7°=180°
7x+12°=180°
7x=168°
x=24°
Because the angles marked 6 and 3x+5 are corresponding angles, they are congruent, so:
<6=24*3+5
<6=77°

Answer:
 C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 ) 
= -21x + 15 
step 2 : then it will be 21x + 15 = 87 + 3x 
step 3 : switch between the odds into like this 
 21x - 3x = 87 - 15 
 
step 4 : subtract it all 
 18x = 72 
step 5 : bring 18 to the other side 
 x = 72/18 
step 6 : to find the ans of x is just calculate them 
 x = 72 ÷ 18 
 = 4 
Or you can do like these ⬇️ 
 
-3 ( 7x - 15 ) = 87 + 3x 
 21x + 15 = 87 + 3x 
 21x - 3x = 87 - 15 
 18x = 72 
 x = 72/18 or 72÷18 
 x = 4
