ABC is a triangleAB = 8.4 cm Angle BAC = 54°
Angle ABC = 90°Calculate the value of x.
Leave your answer to 2 decimal places

yes

step-by-step explanation:

give me the question

\

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: procent 54 wynosi 33,33%

the answer to the expression is 83
