Can you guys me find the value of x

b

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, thus

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

90 + 148 + 3x + 10 + x + 112 = 540, that is

360 + 4x = 540 ( subtract 360 from both sides )

4x = 180 ( divide both sides by 4 )

x = 45 → b

answer: answer: d) v= 1/6 bh
