Weby = 3x + 20. We don’t know y, but we know that the adjacent angle to y is 7x – 30. Since y and its adjacent angle are supplementary, they add up to 180, which gives us the equation: y + (7x – 30) = 180. y = 210 – 7x. Combining both of our equations, we get: y = 3x + 20 [since y and 3x + 20 are corresponding angles] Webtwo angles whose measures have the sum of 90 degrees If two angles have a sum of 90 degrees, then they are complementary. If two angles are complementary, then they …
Special right triangle - Wikipedia
WebAngle-based special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π / 2 radians, is equal to the sum of the other two angles.. The side lengths are generally deduced from the basis of the unit circle or other … Web28 mrt. 2024 · Two angles are called complementary angles if the sum of their measure equals 90°.
