Answer:
28 units²
Step-by-step explanation:
→ Work out the size of the triangle if it was a full rectangle
Height = 4 and Base = 2
→ Work out area of triangle
0.5 × Height × Base ⇒ 0.5 × 4 × 2 ⇒ 2 × 2 ⇒ 4
→ Minus the area of the triangle from the "imaginary full' rectangle
Area of rectangle = Length × Width ⇒ 8 × 4 ⇒ 32
32 - 4 = 28
Answer:
B
Step-by-step explanation:
Base= x
Height= 4+x
Area = (1/2)(x)(4+x) = 6
Hence, quadratic equation is,
(x)(8+2x) = 12
Answer:
Step-by-step explanation:
(2,4)
Step-by-step explanation:
x=(180-x)-172
x+x=180-172
2x=8
x=4(angle)
180-4=176(supplementary angle)
