Geometry help? Find the values of the variable I know it would be 115.5 but how do I get that answer
dybincka [34]
Subtract 128.5 from 180 degrees and you get 51.5. Then add 51.5 plus 13, you get 64.5. Subtract 64.5 from 180 and you get 115.5. A triangle's angles all added together equals 180.

Find a third number so that numbers form a right triangle 13,85
crimeas [40]

Answer:

The third number is 84

Step-by-step explanation:

Given two numbers as 13 , 85

To make the triangle to be right angle , Pythagoras theorem is applied ,

i.e H² = P² + B²

    Here H = 85 ,

    Let perpendicular = x and base = 13

So, P² = H² - B²

Or,  x² = 85² - 13²

Or,  x² = 7225 - 169

Or,  x² = 7056

i.e x = \sqrt{7056} = 84

Hence, the third number to make it right triangle = 84   Answer
