The answer should be 4. Take note of the pattern of unit digits of 2^n.

2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32

Every 4 powers, it rotates 2, 8, 6, 4. Since 2020 is divisible by 4, the answer is 4.

9 over 3x = 4 over x + 2

Elan Coil [88]

The equation that we have been given is:

$\frac{9}{3x}$ = $\frac{4}{x+2}$

In order to solve for the value of 'x', we'll have to use cross-multiplication.

Cross-multiplication is a method in which the numerator of one fraction is multiplied by the denominator of another fraction that it is equal to.

Let's cross-mutliply the numerators and denominators:

$\frac{9}{3x}$ = $\frac{4}{x+2}$

9*(x+2) = 4*(3x)

Distribute the numbers into the parentheses.

9x + 18 = 12x

Simplify by subtracting both sides by 9x:

9x - 9x + 18 = 12x - 9x

0 + 18 = 3x

18 = 3x

3x = 18

Divide both sides by 3:

$\frac{3x}{3}$ = $\frac{18}{3}$

Giving triangle and m what is m >b

Gelneren [198K]

Since you know the triangles are congruent/equal, you know that:

m∠A and m∠X are congruent and have the same angle, and so does:

m∠B and m∠Y

m∠C and m∠Z

A triangle is 180°. (the 3 angles have to add up to 180) To find m∠B, you can do this:

m∠A + m∠B + m∠C = 180°

21° + m∠B + 35° = 180° Subtract 21 and 35 on both sides

m∠B = 124° your answer is C
