Answer:
−8x^4 + 5x^3 + x^2
Step-by-step explanation:
3x^3 + x^2 + 2 (x^3 − 4x^4)
Apply the distributive property.
3x^3 + x^2 + 2x^3 + 2 (−4x^4)
Multiply −4 by 2.
3x^3 + x^2 + 2x^3 − 8x^4
Simplify by adding terms.
Add 3x^3 and 2x^3.
5x^3 + x^2 − 8x^4
Simplify the expression.
Move x2.
5x^3 − 8x^4 + x^2
Reorder 5x^3 and −8x^4.
−8x^4 + 5x^3 + x^2
Answer:
m ∠ W is 58.2°
Step-by-step explanation:
Given:
XY = 15
WZ = 22
∠ XZY =25°
To Find:
m ∠ W = ?
Solution:
In right angle triangle Δ XZY, by Sine identity we have

∴ XZ = 35.49
Now in right angle triangle Δ WZX, by tangent identity we have

∴m ∠W =58.2°
Answer:
B. The statement is false. This is true only if θ is an acute angle in a right triangle.
Step-by-step explanation:
Trigonometric ratio formula can only be applied to define the relationship between the angles of a right triangle and its side lengths.
Therefore, it is impossible to define or find the tan θ of "any triangle". It only applies to right angled triangles.
In the case of a right triangle, given a reference angle, θ, tan θ = side lenght opposite to θ ÷ side lenght adjacent to θ (tan θ =
.
A right triangle has two acute angles and 1 right angle that which is 90°.
Therefore, we can conclude that:
"B. The statement is false. This is true only if θ is an acute angle in a right triangle."
