Answer:

C = ~50 deg

Step-by-step explanation:

Apply the cosine theorem:

cos(C) = (CA^2 + CB^2 - AB^2)/(2*CA*CB)

= (7.5^2 + 6.5^2 - 6^2)/(2*7.5*6.5)

= 0.6410

=> C = ~50 deg

Hope this helps!

Well, their speeds are ( $V_1$ is Jack's speed, and $V_2$ is Richard's.
$V_1 = \frac{1}{5} houses/day \\ V_2 = \frac{1}{7} houses/day \\ V = V_1 + V_2 = \frac{1}{5}+\frac{1}{7} = \frac{7+5}{35} = \frac{12}{35}$
They, together, can paint 12 houses in 35 days. To get a single house, we only have to calculate $\frac{35}{12}$ which is very close to 3 (a bit below)
