Question

What is the value of x? Enter your answer in the box. x = An equilateral triangle X Y Z with base X Y slightly inclined with vertical and vertex Z is in left of the base. Side X Y and Y Z and Z X are labeled with single tick mark. Angle X Y Z is labeled as left parenthesis 2 x minus 4 right parenthesis degrees. Angle X Y Z is labeled as 5y degrees.

Answer 2

The value of x = 8

Given that,

Equilateral Δ RTS,

Base = RT

Vertex = S

RT = TS = SR

∠RST $= (7x + 4)$°

∠RTS $= (8y +12)$°

As we know,

RT = TS = SR

∵ ∠R = ∠S = ∠T = 60°

So,

∠RST $= (7x + 4)$° = 60°

⇒ $7x = 60-4$

∵ ∠RST $=56/7$ $= 8$

Thus, the value of $x = 8$
