the diagram shows a triangle. what is the value of x? x = °
Answer
Explanation:
Step1: Recall angle - sum property
The sum of interior angles of a triangle is 180°. So, 10x + 54°+ 96°= 180°.
Step2: Simplify the left - hand side
10x+(54 + 96)°=180°, 10x + 150°= 180°.
Step3: Isolate the variable
Subtract 150° from both sides: 10x=180° - 150°, 10x = 30°.
Step4: Solve for x
Divide both sides by 10: x = $\frac{30}{10}$, x = 3°.
