Answer:
length of other leg = 20'
Step-by-step explanation:
Given:
One leg of triangle let it be base of triangle = 21'
Hypotenuse = 29'
To Find:
Third leg =perpendicular = ?
Solution:
Given is a right angled triangle with two of its sides given to us
We have Pythagoras theorem for right angled triangle and according to it
Pythagoras theorem is
for a right angled triangle
(hyp) ² = (perp)²+(base)²
We have the values of hyp and base
putting them in the equation we get
(29) ² = (perp) ²+(21) ²
841 = (perp) ² + 441
subtracting 441 from both sides we get
841 - 441 = (perp) ² + 441 - 441
400 = (perp)²
or
(perp) ²=400
Taking square root of both sides
it gives us
perp = ± 20'
As it is length and it can not be negative so
perp = 20'
or
length of other leg = 20'
Answer:
Step-by-step explanation:
sina=opposite/hypotenuse=7/25
cosa=adjacent/hypotenuse=24/25
tana=opposite/adjacent=7/24
sinc=opposite/hypotenuse=24/25
cosc=adjacent/hypotenuse=7/25
tanc=opposite/adjacent=24/7
You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.
