What is the value of x? enter your answer in the box. x =

The triangle is an equilateral triangle because all sides are congruent therefore, each angle of the triangle is 60 degrees.

2x - 4 = 60 (Add 4 to each side)

2x = 64 (Divided by 2 to each side)

x = 32 degrees

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
