The diagram of the ladder leaning on a wall is shown below
We will use the trigonometry ratio for cosine to solve for 'x'
We choose the cosine ratio because we have the angle, 61° and the side adjacent to the angle
, rounded to 2 dp
Hi Brainiac
1/2(2x-6) = -6
We need to distribute
(1/2)(2x) + (1/2)(-6) = -6
2x/2 + -6/2 = -6
x - 3 = -6
x = -6 + 3
x = -3
Thus, The answer is D
I apologize for the late answer :(
The given formula is f(t) = 0.4t
They want to solve for f(10), replace t in the formula with 10"
f(10) = 0.4(10)
Multiply:
f(10) = 4 centimeters.
If this is the question I'm thinking it is... then....
The part swimming and cycling = 1/4 + 3/5
= 17/20
The part remaining after swimming and cycling
= 1/1 – 17/20
= 17/17 – 17/20
= 3/20
if 3/20 part = 3600
then 1 full part = 3600 × 20/3 = 24000
