Step-by-step explanation:
Hey there!
Use cos ratio to find the value of 'a'.
As per given, we can state that it is a Right angled triangle, so taking 38° reference angle.
We get;
p = AC
b = 6
and h= a
Here, Use the value of b, h and 38° angle to find the value of a.
[tex] \cos(38° ) = \frac{b}{h} [/tex]
[tex] \cos(38°) = \frac{6}{a} [/tex]
[tex]0.7881 = \frac{6}{a} [/tex] [ cos(38°=0.7881]
[tex]0.7881a = 6[/tex]
[tex]a = \frac{6}{0.7881} [/tex]
Therefore the measure of a is 7.61 Or 8.
Hope it helps..
