the measures of the angles of a triangle are shown in the figure below. solve for x. answer attempt 1 out of 2
Answer
Explanation:
Step1: Recall angle - sum property
The sum of the interior angles of a triangle is 180°. So, we have the equation $(2x + 16)+48 + 90=180$.
Step2: Simplify the left - hand side
Combine like terms: $2x+(16 + 48+90)=2x + 154$. So the equation becomes $2x+154 = 180$.
Step3: Isolate the variable term
Subtract 154 from both sides: $2x=180 - 154$, which gives $2x = 26$.
Step4: Solve for x
Divide both sides by 2: $x=\frac{26}{2}=13$.
Answer:
$13$
