Two Ships leave a harbor together traveling on courses that have an angle of 124 ° between them. If they travel 550 miles, how far apart are they to the nearest mile?

My math is online and the helper says that sin∅= y/r= (5√74)/74 = 144.5° . how do u convert that fraction into degrees. I did try the inverse of ∅=sin-1(y/r) , but for my example that...

a bridge is built in the shape of a parabolic arch. The bridge arch has a span of 196 feet and a maximum height of 30 feet. find the height of the arch at 15 feet from center.

I am not sure how to do this. So far I did Cos(x^(1/2)^3 So I did the chain rule to make Cos(u) where u = x^(3/2) Then I got -Sin(sqrtx)^3*(3/2)x^(1/2) Which then simplifies to (-3Sin(sqrtx)(sqrx))/2 What...

From a hot air balloon 4 km high, a person looks east and sees one town with angle of depression of 16°. He then looks west to see another town with angle of depression of 84°.

How do I write as a algebraic expression

Write the following in terms of sin (theta) only: 2sec(theta)tan(theta)+tan^2(theta)

Calculate, correct to 2 decimal place accuracy, the area of a sector which has an included angle of 75degrees and a radius of 6.2 m.

I believe it is because there are no x factors in the numerator but unsure.
