Answer: Main Street make 41° angle with Birch Avenue.

Step-by-step explanation:

Since we have given that

Length of State Street = 75 m

Length of Birch Street = 115 m

So, we need to find the angle between Main and Birch Street.

We will use "Sine" as we have Perpendicular and hypotenuse given.

$\sin \theta=\dfrac{75}{115}\\\\\sin \theta=0.652\\\\\theta=\sin^{-1}(0.652)\\\\\theta=40.7\\\\\theta\approx 41^\circ$

Hence, Main Street make 41° angle with Birch Avenue.

Cos theta = 75/115
theta = cos^-1 (75/115)
theta = 49.2 degrees

Kaleb makes an investment at 5.2 percent simple interest. At the end of 1 year, the total value of the investment is $2419.60. H

Dafna11 [192]

The future amount of the current deposit given that the interest is simple and yearly is computed through the equation,
F = P x (1 + in)
where P is the principal amount, F is the future amount, i is the interest (in decimal form) and n is the number of years.

In this certain problem, we substitute the known values to the equation and solve for P,
2419.60 = P x (1 + (0.052)(1))
P = 2300
Thus, the initial investment was worth $2,300.

Step-by-step explanation:

When squaring the number 5 (i.e $5^2$ ) the answer is 25. $5^{2}$ is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
