Sin and cos are related by the following identity:
sin (90 - θ) = cos(θ)
The value of θ in the given case is 48, so the equation becomes:
sin(90 - 48) = cos(48)
sin (42) = cos(48)
Thus, in the given question value of <span>ø will be 42 degrees.</span>

Answer:
6.3 years
Step-by-step explanation:
The formula for depreciation is
Where P is the initial value, A is final value, t is duration in years and r is rate in deximal point. Substituting 55, 500 for P and 20, 000 for A, 0.15 for rate, r then
Therefore, it requires about 6.3 years
Solve for y. Do that by adding the opposite of the x-term, then dividing by the coefficient of y.
11y = 12x - 8
y = (12/11)x - 8/11
The slope is 12/11.
The y-intercept is -8/11.
