Solve triangle ABC if A = 50°, a = 10, and b = 20. If no triangle exists, explain why.

Dahasolnce [82]

Answer:

No triangle exist

Step-by-step explanation:

step 1

Find the measure of angle B

Applying the law of sines

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

substitute the given values

$\frac{10}{sin(50^o)}=\frac{20}{sin(B)}$

$sin(B)=20(sin(50^o))/10$

$sin(B)=1.532$

Remember that

The maximum value of the sine is 1

therefore

No triangle exist
