The answer is 80 degrees. As you can see, the triangle is an isosceles triangle and both sides of the triangle equal 14. If both of the sides are congruent then the opposite angles are also congruent as well. Which means the 50 degrees in the left angle is congruent to the right angle, 50. Since triangles add up to 180 degrees, the answer for x would be 80.

Hope this helped :)

Answer:

a) $370

b) $305 is from interest; $3695 comes from deposits

Step-by-step explanation:

(a) The formula variables are not defined here, so choosing the appropriate formula is difficult. I worked through the "A =" formula because I'm used to seeing a formula in which A is the payment amount. Not so, here.

Here, P is the payment amount. Since you're asked to find the amount of payment, you want to choose and evaluate the "P=" formula. Payments and compounding are 2 times per year, so n=2, and the term is 5 years, so t=5. The interest rate, r, is 3.5%, or 0.035.

Then your formula evaluates to ...

... P = A((1 +r/n)^(nt) -1)/(r/n) = 4000·0.0175/(1.0175^(2·5) -1) ≈ 369.50

Part A wants the amount rounded up to the nearest dollar, so $370.

(b) 10 payments of $369.50 will total $3695.00. This is the amount from payments. The remainder, $4000 -3695 = $305 is from interest.
