Question

What are the values of a and b?

Answer 1

Answer:

$A= \frac{400}{21} B=\frac{580}{21}$

Step-by-step explanation:

You just have to remember the rules of the triangles in order to be able to solve this:

The rule of trigonometry that you will have to use is a is similie to 20, B is simile to 29 and 20 is 20.

So you would have to put them like this:

$\frac{21}{20}= \frac{20}{a}= \frac{29}{b}$

You just have to clear the equations for A and B:

$a=\frac{20*20}{21}=\frac{400}{21}\\ b=\frac{29*20}{21} =\frac{580}{21}$

So that would be your answer.

Answer 2

Try this option:
1. rule is: 21/20=20/a=29/b;
2. 21/20=20/a, ⇒ a=400/21;
3. 21/20=29/b, ⇒ b=580/21.
