This is a problem on right triangle trigonometry. The hypotenuse is 60 feet and the unknown side is opposite the given 75-degree angle. Given these values, we will use the sine function. That is 
     sin\left(75^{\circ} \right)=\frac{h}{60}

     h=60\cdot sin\left(75^{\circ} \right)=58\:feet

<span>The maximum height that the ladder can safely reach is closest to 58 feet. </span>

Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p

part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2
54-2

The equation of the function is Y=4x+5.Find the value of y when<br> x=3<br> x=-2
natita [175]
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

The equation of the function is y = 4x + 5. Find the value of y when

x = 3

x = -2

<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>

<h3>Given:-</h3>

y = 4x + 5 [Equation]

<h3>To Find:-</h3>

The value of y when x = 3 , x = -2

<h2>Solution:-</h2>

y = 4x + 5 [Given equation]

\therefore When x = 3 ,

y = 4 × 3 + 5 [Value of x is 3]

y = 12 + 5

<h3>y = 17 [Answer]</h3>

Again, when x = -2 ,

y = 4 × (-2) + 5 [Value of x is -2]

y = -8 + 5

<h3>y = -3 [Answer]</h3>
