Question

A ladder is placed 30 inches from a wall. It touches the wall at a height of 50 inches from the ground.

The angle made by the ladder with the ground is _____ degrees, and the length of the ladder is _____ inches.

Answer 1

To find hypotenuse , use Pythagorean theorem.
And to find the value of angle use sine inverse function.

Answer 2

Answer:

no= length of the ladder

BC= distance between wall I lodder + 30

AB= length of wall =

AABC is a right angled triangle by pythagorean theorema

ACE AB²+ BC²

AC² = 30² +50² AC ² = 900+2500

AC² = 3400

AC= √3400 C 58.3

dength of the wall is 58.31 k

Angle made by the ground Le ladder with

the value of an

30

C

The method to find angle in a right

angled triangle by using sin", cos", tou! sint of approx to Le 583

value of angle C is sin 50 58.3

sin 0.8576 31°. CRounded value.) so the ladder makes angle of 31⁰ with the

ground
