Answer:
140+x+x = 180°(co-interior angle)
140+2x=180°
2x=180°-140°
2x = 40°
x = 40°/2
x = 20°
check:
140+20+20 = 180
180=180
Answer:
56 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
A = 1/2 (14) (8)
A = 56 cm^2
The sum of the 3 interior angles must be 180 degrees.
Thus, 42 + 4p + 2p = 180 degrees, or 6p = 138 degrees. Then p = 23 degrees.
