Answer:
So, BC = 5.6 cm
Step-by-step explanation:
Since its a right angled triangle,
taking 62 as reference angle,
cos62 = b/h
or, cos62 = AB/BC
or, cos62 = AB/12cm
or, cos62×12cm = BC
so, BC = 5.63
x=8
Explanation:
the opposite side is 72, which means I have to make 9x end up equaling 72.
72÷9
////
72/9
=8
9×8=72
<u>Therefore</u>
the value of x is 8.
