which angles of the triangles measure to a 90 degree
Answer:
A right angle has a value of 90 degrees (90∘). A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry.
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b). Side a may be identified as the side adjacent to angle B and opposed to (or opposite) angle A. Side b is the side adjacent to angle A and opposed to angle

Find the complement of set B in-universe U.
U is the set of natural numbers less than or equal to 8
B is the set of even factors of 8
Answer:
B' = {1, 3, 5, 6, 7}
Step-by-step explanation:
U = {1, 2, 3, 4, 5, 6, 7, 8}

3. Which is the best description of an extraneous solution?
Answer: A solution that results in a false statement when substituted back into the original equation.
Step-by-step explanation: An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.
