When were the forces in the pair of pulling at right angles to each other for the values a = 2.9 which is a leg of right triangle and a value c = 4.2 which is a hypothesis find the length of the other leg be to the nearest

The Pythagorean theorem tells you the other leg is

... √(c² - a²) = √(4.2² -2.9²) = √9.23 ≈ 3.038 ≈ 3.0

There is insufficient information to do anything with forces.

easy math just plug in a and b

step-by-step explanation:

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
