Find the length of the unknown side. Round your answer to the nearest tenth. (4 points) Image of a right triangle with a leg lab

Anika [276]

using pythagorean theorem

a^2 + b^2 =c^2

a^2 +8^2 =14^2

a^2 +64 = 196

subtract 64 from each side

a^2 = 132

take the square root of each side

a^2 = sqrt (132)

a=11.48912529

a =11.5

A 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft. To make the ramp less steep,

Anika [276]

Answer:

The length of new ramp is 49.03 ft.

Step-by-step explanation:

It is given that 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft.

If the horizontal distance is doubled, then the horizontal distance is 48 ft. The height remains same. Therefore the height of ram is 10 ft.

Use pythagoras in new right angle triangle.

$hypotenuse^2=base^2+perpendicular^2$

$(AE)^2=(AD)^2+(ED)^2$

$(AE)^2=(48)^2+(10)^2$

$(AE)^2=2304+100$

$AE=\sqrt{2404}$

$AE=49.0306027\approx 49.03$

Therefore the length of new ramp is 49.03 ft.
