PLS HELP ILL GIVE BRAINLIST!
RideAnS [48]

Answer:

The length of AP will be 14 units.

Step-by-step explanation:

As P is the centroid of ΔABC as shown in question figure.

As the side AB of the triangle has the midpoint D, the side AC of the triangle has the midpoint F and the side BC of the triangle has the

midpoint E.

Hence, CD, BF and AE being medians of ΔABC.

The point of intersection of these medians will be the centroid of the triangle. Hence, P is the centroid of ΔABC

According to rule, the centroid point of the triangle ΔABC divides each median into two segments in the ratio 2 : 1.

So,

AP = \frac{2}{3} AE

As the value of AE = 21

So,

AP = \frac{2}{3} (21)

AP = 14

So, the length of AP will be 14 units.

Step2247 [10]

By using trigonometric relations, we will see that x = 9.97°.

<h3>How to find the missing angle?</h3>

First, we need to find the bottom cathetus of the smaller triangle, we will use the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus).

Where:

  • θ = 26°
  • Adjacent cathetus = k
  • Opposite cathetus  = 55ft.

Replacing that we get:

Tan(26°) = 50ft/k

Solving this for k, we get:

k = 55ft/tan(26°) = 112.8 ft

Now, we can see that the longer triangle adds 200ft to this cathetus, so now we will have:

  • angle = x
  • opposite cathetus = 55ft
  • adjacent cathetus = 112.8ft + 200ft = 312.8ft.

Then we have:

Tan(x) = (55ft/312.8ft)

Using the inverse tangent function in both sides, we get:

x = Atan(55ft/312.8ft) = 9.97°
