Answer:

Mrs. Storz must give 45 minutes

Step-by-step explanation:

Create a proportion:

t = total time given for all questions

\frac{3}{7.5} = \frac{18}{t}

Cross multiply:

3t = 135

Divide both sides:

3t/3 = 135/3

t = 45

Does anyone know how to solve this?
Bezzdna [24]

Use this version of the Law of Cosines to find side b:

b^2 = a^2 + c^2 − 2ac cos(B)

We want side b.

b^2 = (41)^2 + (20)^2 - 2(41)(20)cos(36°)

After finding b, you can use the Law of Sines to find angles A and C or use other forms of the Law of Cosines to find angles A and C.
