WebQuestion: 4.7 Theorem of Right Triangles Let ABC be a triangle. CBC is a right angle if and only if we have the following identity: AC∧2=A∧2+B∧2 Given: ABC is a triangle in which ∠ABC=90∘. By construction, BD⊥AC. WebThat is, the sum of the two acute angles in a right triangle is equal to #90^o#. If we know one of these angles, we can easily substitute that value and find the missing one. For example, if one of the angles in a right triangle is #25^o#, the other acute angle is given by: #25^o +y=90^o# #y=90^o-25^o# #y=65^o#

WebMar 26, 2024 · Triangle ABC is a right triangle. Triangle A B C. Angle A is x degrees, B is 90 degrees, C is (x minus 10) degrees. The exterior angle to angle C is (2 x + 40) degrees. Which equations can be used to find the value of x? Check all that apply. 1. x + 90 + (x minus 10) = 180 2. x + 90 + (2 x + 40) = 180 3. 2 x + 80 = 180 4. x + 90 = 2 x + 40 5.
