What is the measure of angle x? Help me plz

x  =  60 ∘

Explanation:

As indicated by the markings, all the sides of this triangle are equal, and therefore all the angles of this triangle must be equal as well.

Let  x  be an angle,

so by the triangle sum theorem, we can say that:

3  x  = 180 ∘

x  =  60 ∘

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
