LHS = RHS
Step-by-step explanation:

Since

Therefore,

Therefore LHS = RHS
Answer:
x = 60°
Step-by-step explanation:
Use special triangles.
Starting with an equilateral triangle (all angles at 60°) with the side length of 2. Drop an altitude from one of the vertices to cut in half and make a right - triangle.
The hypotenuse length is 2. The base length, because it was cut in half, is 1. The height can be found with the Pythagorean theorem, which is √3.
The ratio for tangent is opposite over adjacent.
Since √3 = √3 / 1, the angle must be the one as marked in the picture.
Remember this triangle came from an equilateral triangle, so that angle is 60°. It was not cut in half, unlike the top angle which is 30°.
Answer:
18x^5 +28x^2
Step-by-step explanation:
20x^2 + 14x^5 + 8x^2 + 4x^5
Combine like terms
20x^2 + 8x^2 + 4x^5+ 14x^5
28x^2 + 18x^5
We usually write the highest power term first
18x^5 +28x^2
Answer:
X=44
Step-by-step explanation:
I’m pretty sure it’s h because the lines meet in the x axis
