Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 838383 centimeters tall and the ramp is 158158158 centimeters long.

134.44 cm

Step-by-step explanation:

Given that:

Length of ramp, = 158 cm

Height of truck, = 83 cm

The distance from end of ramp to base of truck ;

Using Pythagoras rule :

The diagram is in the picture attached ;

Opposite = sqrt(hypotenus² - adjacent²)

d = sqrt(158² - 83²)

d = sqrt(24964 - 6889)

d = sqrt(18075)

d = 134.44 cm

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
