Step-by-step explanation:
Answer:
31
Step-by-step explanation:
Recognize that all angles of a triangle add up to 180 degrees, so your equation would be x + 16 + x + 24 + 78 = 180.
<em>Step 1: Combine like-terms.</em>
2x + 118 = 180
<em>Step 2: Subtract 118 from both sides to isolate the variable.</em>
2x = 62
<em>Step 3: Simplify</em>
x = 31
X=-14
After you take the -2 then change it to +2 under the -16 your answer should be X=-14
Area=3.14*r²
Since I don't know the radius there's the formula
