Answer:

23.54 m

Step-by-step explanation:

Applying

cos∅ = adjacent(A)/hypotenuse(H)

cos∅ = A/H................ Equation 1

make H the subject of the equation

H = A/cos∅............ Equation 2

Given: A = 15 m, ∅ = 25°

Substitute into equation 2

H = 15/cos25

H = 16.55 m

Also,

tan∅ = opposite(O)/Adjacent(A)

tan∅ = O/A............Equation 3

Make O the subject of the equation

O = Atan∅.......... Equation 4

Substituting into equation 4

O = 15(tan25°)

O = 6.99 m.

From the diagram,

The height of the goal post before snap = H+O

The height of the goal post before snap = 16.55+6.99

The height of the goal post before snap = 23.54 m

5. The length of a rectangular swimming pool is 50 yards, and the width of the pool is 16

d1i1m1o1n [39]

The answer is C. I got this by doing a^2 + b^2= c^2. 50^2 + 16^2=c^2, 2500 + 256 = c^2, 2756 = c^2, then you take the square root of 2756 and that gives you your answer 52.50 yards. Hope this helps :D

Slope intercept! Please help! Will mark brainliest.

avanturin [10]

3) y = $-\frac{1}{2}$ x + 3

Slope-intercept form is y = mx + b when m is the slope and b is the y-intercept

b = 2 (line hits y-axis at 2)

m = $\frac{rise}{run} or\frac{change.in.y}{change.in.x}$ so $\frac{1}{2}$ and the line is negative, so $-\frac{1}{2}$

Write our equation by putting the parts together, and we get:

y = $-\frac{1}{2}$ x + 3

4) y = $-\frac{2}{3}$ x - 1.67

Point slope form is y - y1 = m (x - x1) when y1 is the y coordinate of the point, m is the slope, and x1 is the x coordinate of the point

y - y1 = m (x - x1)

Finding the slope (same as above) results in $-\frac{2}{3}$
