Question

find the value of sin45° + cos45°-tan45°.​

Answer 1

Answer:

A 45°-45°-90° triangle is an isosceles triangle, so the opposite side and the adjacent side are equal. As a result the Sin45° = Cos45° and Tan 45° = 1 because tan is a ratio of the opposite side divided by the adjacent side, and these sides are equal.

As a result: Sin 45 degrees/cos 45 degrees = 1

tan 45 degrees = 1

1 + 1 = 2
