-93.8 – 35.5
here both the numbers are negative , so rule is to add the numbers and keep the negative sign intact,
-93.8 – 35.5= -129.3
SAS because of the vertical angle theorem
y squared equals x squared minus z squared.
Solution:
The given triangle is a right angled triangle.
Hypotenuse = x, Base = y, Height = z
Using Pythagoras theorem, we can find the lengths of the sides of the right triangle.
Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.

Subtract
from both sides of the equation.

Switch the sides

y squared equals x squared minus z squared.
Hence Option B is the correct answer.
Answer:
Step-by-step explanation:
I cannot explain exatly how I did it, but basically you got to see the already acquired numbers to find out what numbers were necessary to get the ones that you already have, hope that the resolution helps you.
