Answer:
Hello! answer: 40
We know 1 angle is 50 degrees so that means the angle across will also be 50 degrees so that means 2 will be 40 degrees cause that is a complimentary angle and complimentary angles add up to 90 Hope this explains well!
Answer: last option.
Step-by-step explanation:
To apply the Distributive property, remember that:

Then, applying this, you get:

Combine like terms means that you need to add the like terms.
Therefore, you get:

You can observe that the expression obtained matches with the expression provided in the last option.
Answer:
1) solve x+1/x = 5






2) solve x³+1/x³

substitute x = 1/4 into the expression





Answer:
sqrt(10) *x
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + (3x)^2 = hypotenuse ^2
x^2 + 9x^2 = hypotenuse ^2
10x^2 = hypotenuse ^2
Take the square root of each side
sqrt( 10x^2) = sqrt(hypotenuse ^2)
sqrt(10) * x = hypotenuse
