Answer:
51
Step-by-step explanation:
We have a right angle in the triangle, that means it is
[tex] {90}^{0} [/tex]
And know that the total angle in a triangle is 180,
Then we can equate the angles to 180
[tex]5q - 4 + 39 + 90 = 180[/tex]
Or we can simplify it and do
[tex]5q - 4 + 39 = 90[/tex]
As the right angle can be subtracted from 180 at once to give 90, we have
[tex]5q + 35 = 90[/tex]
[tex]5q = 55[/tex]
When we take 35 over to the other side and we subtract it from 90.
Later,
[tex]q = 11[/tex],
When we divide both sides by 5,
Putting it back, we have
[tex]5 * 11 - 4[/tex]
Solving, we have
[tex]55 - 4[/tex]
We have, 51
hope it was understandable, also this is a general principle to be applied to this type of question, so hope it was cleared and understood
