Answer:
50°
Step-by-step explanation:
101 + 133 + 76 +x = 360
310 + x = 360
x = 50
It is
the four is multiplied 5 times
20 units
The formula for the area:
A = bh × 1/2
B = 8 units
H = 5 units
8 × 5 = 40
40 × 1/2 = 20
x = 15
These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
