Question

Solve the triangle by finding the missing sides and angles. Round the sides to the nearest 10th and angle to the nearest degree 15 yd 13yd

Answer 1

`{c}^(2) - {b}^(2) = {a}^(2)`

`{15}^(2) - {13}^(2) = {56}^(2)`

`√(56) = 7.5\: yd`

//

`sin = (opp)/(hyp)`

`{sin}^( - 1) = (13)/(15)`

`= 60 \: degrees`

//

`180 - 90 - 60 = 30 \: degrees`
