Answer: x=t/r+s/r
How to:<u> Isolate the variable by dividing each side by factors that don't contain the variable.</u>
Have a great day and stay safe !
To find the value of x, we need to use Pythagorean Theorum.
The equation for Pythagorean Theorum is a^2 + b^2 = c^2.
C^2 is our hypotenuse, or the side that's across from the right angle.
13 is our hypotenuse, and 12 is b.
Since our numbers are not squared, let's square them.
13 x 13 = 169
12 x 12 = 144.
Our equation now is a^2 + 144 = 169
To find a^2, we need to subtract b^2 from c^2.
Subtract 144 from 169.
169 - 144 = 25.
a^2 = 25
Square root both sides.
a = 5.
x = 5.

Answer:
70
Step-by-step explanation:
I suppose its 70 because... 7 + 3 = 10
and 70 + 30 = 100...so the SUM is 100...yet minus 30 would be 70...so
70 is the bigger number...
please let me know if this was right...
hope I helped!
