Solve for x. enter your answer in the box. a = (2y), b = (25x - 15), and c is unknown.

Step-by-step explanation:

This an equilateral triangle, so all angles are equal

:- 180/3 = 60°

So each angle should be equal 60°

<C = 60°

<A = 2y = 60°

y = 60/2

y = 30°

<B = 25x - 15 = 60°

Collecting like terms

25x = 60 - 15

25x = 45

x = 45/25 = 9/5

x = 1.8°

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
