Answer:
1st question: 30
2nd question:78
Step-by-step explanation:
use the formula [tex]A=\frac{ab}{2} sin(y)[/tex]]
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:
[tex]A=(\frac{9*7}{2})Sin73\\=31.5(Sin73)\\=30.1\\=30 (rounded)[/tex]
For the 2nd question, we use the same formula, only this time
a=13
b=14
y=59
so,
[tex]A=\frac{13*14}{2} sin(59)\\A=91*Sin(59)\\A=78[/tex]
