Try out all of your options by filling the the x and y values from each option. You can use either of the two equations to solve

1) 2(2)+3(3) does not equal 5
2) 2(3)+3(2) does not equal 5
3) 2(3)+3(-2) does not equal 5
4) 2(-2)+3(3) equals 5
4.5) Double check your answer by doing the same thing for the second equation // 3(-2)+2(3) does equal zero.

How many triangles are there that satisfy the conditions a =13, b =9, A = 62°?
8_murik_8 [283]

Answer:

Step-by-step explanation:

Alright, lets get started.

Using sin Law,

\frac{sinA}{a}=\frac{sinB}{b}

Plugging the value of a, b and angle A

\frac{sin62}{13}=\frac{sinB}{9}

sinB=\frac{9*sin62}{13}

sinB=\frac{9*0.8829}{13}

sinB=0.61127

taking sin inverse on both sides

B=sin^{-1}(0.61127) =37.68

The may be another value of B that will called B' = 180-37.68=142.32

We will not consider this B' value because the um of angle B' and A will exceeds 180 degree (142.32+62=204.32)

Thats why only one triangle is possible.   :   Answer

Hope it will help :)
