Question

what is the value of s? write your answer as an integer or as a decimal rounded to the nearest tenth. s = \boxed{\circ}

Explanation:

Step1: Apply exterior angle theorem

$76 = 2s + (2s - 10)$

Step2: Simplify the equation

$76 = 4s - 10$

Step3: Isolate the term with $s$

$4s = 76 + 10$
$4s = 86$

Step4: Solve for $s$

$s = \frac{86}{4}$

Answer:

$s = 21.5^\circ$
