Help please I’ll mark brainiest

h = 2.12 , c = 6.93

Step-by-step explanation:

To calculate h:

Apply the cosine identity

To calculate c:

Apply the tangent identity

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
