Question

For the displayed triangle, provide the following value.

b = ?

Answer 1

what triangle?

Answer 2

Find the remaining triangle (sum of all angles in a triangle =180)

Use the Sin Law. (sides a and b)

Answer 3

90+43=133, 180-133=47...

Answer 4

sines law, I mean....

Answer 5

@maddrea_ 47 isn't right, lol...

Answer 6

Yes, the other triangle would be x,
180=90+43+x
x=47

Now,
\(\Huge\color{blue}{ \bf \frac{Sin(A)}{a}= \frac{Sin(B)}{b} }\)

plug in your numbers into the formula,

\(\Huge\color{blue}{ \bf \frac{Sin(43)}{4}= \frac{Sin(47)}{b} }\)
can you solve for b ?
