Unit test. Test your understanding of Pythagorean theorem with these % (num)s questions. The Pythagorean theorem describes a special relationship between the sides of a right triangle. Even the ancients knew of this relationship. In this topic, we’ll figure out how to use the Pythagorean theorem and prove why it works. So angle w plus 65 degrees, that's this angle right up here, plus the right angle, this is a right triangle, they're going to add up to 180 degrees. So all we need to do is-- well we can simplify the left-hand side right over here. 65 plus 90 is 155. So angle W plus 155 degrees is equal to 180 degrees.

Explanation: We know that the sum of all the angles must be 180 and we already know one angle is 90, leaving the sum of x and y to be 90. Solve for x to find y. One third of 21 is 7. Four less than 7 is 3. So if angle x is 3 then that leaves 87 for angle y.Solution. The correct option is A 20∘. In any triangle, we know that the sum of all the angles of a triangle is equal to 180∘. (Angle Sum Property) ⇒ 4x+2x+3x =180∘. ⇒ 9x= 180∘. ⇒ x= 20∘. ∴ the value of x in the given triangle is 20∘.
