Answer:
4√3 feet
Step-by-step explanation:
Here, a ladder is resting against a house makes a 60° with the ground,
Consider x be the distance of the top of ladder from the foot of house and y be the distance of bottom of ladder from the house. ( shown in the below diagram )
Using trigonometric ratio,
We have, length of ladder = 8 ft,
Hence, the house would reach 4√3 feet up.
Answer:
7
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the opposite interior angles
18x+9 = 5x-5 + 105
Combine like terms
18x+9 = 5x +100
Subtract 5x from each side
18x-5x +9 = 5x+100-5x
13x +9 = 100
Subtract 9 from each side
13x +9-9=100-9
13x= 91
Divide by 13
13x/13 = 91/13
x = 7
Simplify the expression.
Exact Form:
37/10
Decimal Form:
3.7
Mixed Number Form:
3 7/13
Well I don't know !
Let's figure it out:
-- The factors of 18 are 1, 2, 3, 6, 9, and 18 .
-- The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30 .
-- The numbers that are factors of both 18 and 30 (the 'common' ones)
are 1, 2, 3, and 6 .
-- The biggest one on that short list (the 'greatest common' one) is 6 .
