Question

the diagram shows a triangle.
what is the value of x?
x = \\(\square\\)°
save answer

Explanation:

Step1: Sum angles to 180°

$34 + 2x + (x - 25) = 180$

Step2: Simplify left side

$34 - 25 + 2x + x = 180$
$9 + 3x = 180$

Step3: Isolate 3x term

$3x = 180 - 9$
$3x = 171$

Step4: Solve for x

$x = \frac{171}{3}$

Answer:

$57$
