PLEASE HELP ME!! I WANT TO CRY

Find the area of each triangle. Round your answers to the nearest tenth. Show all your work

Answer 1

1st question: 30

2nd question:78

Explanation:

use the formula
`A=(ab)/(2) sin(y)`]

Where A is the area, a and b are the two given lengths and y is the given angle.

So,

a=9

b=7

y=73

Plugging those values in, we get:

`A=((9*7)/(2))Sin73\\=31.5(Sin73)\\=30.1\\=30 (rounded)`

For the 2nd question, we use the same formula, only this time

a=13

b=14

y=59

so,

`A=(13*14)/(2) sin(59)\\A=91*Sin(59)\\A=78`
