Answer:

36.81233927

13.02532494

Step-by-step explanation:

You need to use the law of sine for both of them

the law of sine is as follows:

\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}

Question 1:

\frac{15}{\sin(64)}=\frac{10}{\sin(y)}\\y=36.81233927

Question 2:

Let x= AB

Start by solving for the missing angle, 53

\frac{8.4}{\sin(31)}=\frac{x}{\sin(53)}

x= 13.02532494

I will leave you to round the answers

The answer is 6x. You divide 42 by 7. Take out the x. 42 divided by 7 will equal 6.
