Let θ = m∡I
tan θ = 20/21
tan⁻¹ (20/21) = θ
θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
Natural numbers are always rational numbers,
Rational numbers can be defined as numbers that can be represented as a ratio of two integers. All natural numbers can be represented as a ratio because theycan be over one. For example, 3/1 or 19838645752641/1.
This is true
Think of two houses. If we say "the houses are identical" then the corresponding pieces must be the same (eg: the doors must be the same type out of the same material). In this analogy, the houses are the triangles, which are the overall structures. The doors are the angles since they are pieces of the overall structures. This is what CPCTC is saying
CPCTC = Corresponding Parts of Congruent Triangles are Congruent
Once again, the final answer is true.
Simplify by opening the bracket;
x(x^2+6y^2)
=
Answer:
2x
Step-by-step explanation:
[8x² - 4x] ÷ [4x - 2]
[4x(x - 2)] ÷ [2(x - 2)]
[2x × 2(x - 2)] ÷ [2(x - 2)]
2x
