Question

Please help. A triangle has sides of length 7 in and 20 in with an included angle of 64

Answer 1

Given the following information

length1=7 in

length2=20 in

formed angle =64

the height h is given by

`h=20sin(64)`
`h=17.976`

Area of the triangle is

`A=(b*h)/(2)`
`A=(7*17.976)/(2)`
`A=62.916`

units are

`in^2`
