D).
We want x to be greater than or equal to 4.3. The closed circle tells us that it can be equal to 4.3. The ray to the right tells us that we are looking for numbers larger than 4.3.
Answer:
Sine, cosine and tangent
Step-by-step explanation:
Given a right triangle you can find the sine (or cosine, or tangent) of either of the non- 90° angles.
Area of a triangle = (bh)/2
a = bh/2
a * 2 = bh
(a * 2)/b = h
(27 * 2)/6 = h
54/6 = h
9 = h
