Answer:
The length of the ladder = 6.5077 ft
Step-by-step explanation:
Given A ladder leans against the side of a house
Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house
Let 'C' be the point of observation.
Given CA= 16 ft
From right angle triangle
x = 16 × cos 68°
x = 16 × 0.4067
x = 6.5077
x = 6.5 ft
The length of the ladder = 6.5 ft
When multiplying with fractions you can multiply the top and the bottom independantly
5*3 = 15
1*4 = 4
so 5 * (3/4) = 15/4
21 * (-1) = -21
21 + (-1) = 20
Answer:
Step-by-step explanation:
60 -1 1/2 (8) 2
= 60 - 3/2 (8)(2)
= 60 - 3(8)
= 60 - 24
= 36
204 thousands equals to 204, 000 as the mathematical value and expression.
In expanded form
200, 000 + 4, 000 = 204, 000
In word form,
Two hundred and four thousand
