So to start you need to add 7 and 4 to get 11
Then you divide 1650mL by 11 which gets you 150mL
You then times that by 7 to get the ratio of blue paint which is 1050mL and times 150mL by 4 to get the ratio of red paint which is 600mL

Help please ! thank u
KonstantinChe [14]

Given:

In triangle ABC,m\angle A=138^\circ,c=19,a=29.

To find:

The m\angle C.

Solution:

According to the law of sines:

\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}

Taking \dfrac{\sin A}{a}=\dfrac{\sin C}{c}, we get

\dfrac{\sin 138^\circ}{29}=\dfrac{\sin C}{19}

\dfrac{0.66913}{29}\times 19=\sin C

0.4383959=\sin C

Taking sin inverse on both sides, we get

\sin{-1}0.4383959=C

26.001577^\circ=C

C\approx 26^\circ

Therefore, the correct option is b.
