Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
Answer:
7
Step-by-step explanation:
Using the exact values for
cos45° = and tan60° = , then
2(cos²45° + tan²60°)
= 2( ( )² + ( )² )
= 2( + 3 ) ← distribute
= 1 + 6
= 7
