hi ☺️
your answer is:
sin(x)=a/c
cos(x)=b/c
x=35°
so that:
sin(35)=a/14
a=14sin(35)
a=-5•9cm
And
cos(35)=b/14
b=14cos(35)
b=-12.6cm
so the area of triangle:
Area=1/2(base×hight)
=1\2(b×a)
=1\2(-5.9×-12.6)
Area=37.17cm^2
and the Perimeter of the triangle:
The sum of its three sides
p=a+b+c
= 14+(-5.9)+(-12.6)
=-4.5cm
