Question

find the value of x.
(5x + 20)°
50°
e h g
x =

Explanation:

Step1: Recall angle - sum property

The sum of angles on a straight line is 180°. So, \((5x + 20)+50=180\).

Step2: Simplify the left - hand side

Combine like terms: \(5x+(20 + 50)=180\), which gives \(5x+70 = 180\).

Step3: Isolate the term with x

Subtract 70 from both sides: \(5x=180 - 70\), so \(5x=110\).

Step4: Solve for x

Divide both sides by 5: \(x=\frac{110}{5}\).
