ok so since the total measurement is 180° and you know that 1 of the sides is 40° and the other 2 are the same you will just need to subtract 40 from 180 and split that in half
here's the formula

therefore
x=70°
The answer is 6 since the legs should be the same in a 45 45 90 triangle
Domain is all the values that x can take in the function f(x).
Here, y = x^2
or y = f(x) = x^2
here, x can take any real value. So all real numbers are the domain of f(x).
Domain of y = R
R mean real numbers.

Answer:
Step-by-step explanation:
First, find a common denominator. Fractions can only be added when there is a common denominator.
1/10 & 1/5... 1/10 & 2/10
1/10--2/10
Subtracting two negatives is the same as adding a positive.
1/10+2/10
Final Answer: 3/10
Have a great day!
