Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a flagpole, as shown below:

Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a flagpole. Angle ADC measures 45 degrees, and angle BDC measures 30 degrees. The length of DC is 5 multiplied by square root of 3.

Angle ADC measures 45°, and angle BDC measures 30°. What is the distance between the points A and B on the flagpole?

3.66 feet
13.66 feet
8.66 feet
5 feet

Given that the measure of ∠ADC = 45° and ∠BDC = 30° and the length of DC is 5√3 feet

We need to determine the distance between the points A and B on the flagpole.

Distance between BC:

The distance between BC can be determined using the Pythagorean theorem.

Thus, we have;

Substituting the values, we get;

Simplifying, we get;

Thus, the length of BC is 5 feet.

Distance between AB:

The distance between AB can be determined using the Pythagorean theorem.

Thus, we have;

Substituting the values, we get;

Simplifying, we get;

Thus, the distance between AB is 3.66 feet

Hence, Option A is the correct answer.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

true
