If anyone knows how to do triangle sum and angle theorems, please help. I need this done ASAP. Please.

Step-by-step explanation:

We have a right angle in the triangle, that means it is

And know that the total angle in a triangle is 180,

Then we can equate the angles to 180

Or we can simplify it and do

As the right angle can be subtracted from 180 at once to give 90, we have

When we take 35 over to the other side and we subtract it from 90.

Later,

,

When we divide both sides by 5,

Putting it back, we have

Solving, we have

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
