On a piece of paper, use a protractor and a ruler to construct △abc△abc with ab=8 cmab=8 cm , m∠a=70°m∠a=70° , and m∠b=55°m∠b=55° . what is acac ? 4 cm 6 cm 8 cm 12 cm

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
