65-15= 50

50 divided by 2 is 25

so there are 25 girls

Their could be 25 girls and 40 boys, because then there would be an equal mont of girls and boys until you add 15 more boys. 25+40=65

A new cell tower is being constructed and needs a guy-wire connected 180 feet up the tower and it needs to make an angle of 52°

nevsk [136]

Answer:

228.42 ft

Step-by-step explanation:

To solve for this question, we would be applying the Trigonometric function of Sine.

Sin theta = Opposite/Hypotenuse

Theta = 52°

Opposite = 180ft

Hypotenuse = Length of the wire = x

Hence:

sin 52 = 180/x

x = 180/sin 52

x = 228.42327871 ft

Approximately = 228.42 ft

Urgent please help..

Alexxx [7]

Answer:

x ≈ 13.5

Step-by-step explanation:

Using the sine rule in the triangle, then

$\frac{sin34}{x}$ = $\frac{sin27}{11}$ ( cross- multiply )

x × sin27° = 11 × sin34° ( divide both sides by sin27° )

x = $\frac{11sin34}{sin27}$ ≈ 13.5 ( to the nearest tenth )
