Answer:
whats the question and all of these triangles have a right angle so they are right triangles
Answer: 1. sqrt(19); 2. sqrt (96); 3. sqrt (105); 4. sqrt (28)
Step-by-step explanation: All you have to do is use Pythagoras' Theorem.
So, e.g. in question 1, the equation would be x^2 + 9^2 = 10^2.
x^2 = 100 - 81
x^2 = 19
Therefore, x = sqrt (19) or (19)^1/2
BTW, sqrt means square root.
And now you apply it for everything else.
