Answer:

Step-by-step explanation:

Vertical angles are congruent

m < ABY = m < ZBU

Substitute in their known values

(3x - 5)° = (2x + 40)°

Add 5° to both sides of the equation

3x = 2x + 45°

Subtract 2x from both sides of the equation

x = 45°

Hope this helps :)

Answer:

$\frac{11}{42}$ or 26.19%

Step-by-step explanation:

If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...

13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53

Therefore, the probability that the number formed is a prime would be $\frac{11}{42}$ which if we divide and multiply the decimal by 100 we get the probability in percentage form.

$\frac{11}{42}$ = 0.2619

0.2619 * 100 = 26.19%

Finally, we can see that the probability of this happening is 26.19%

Use the distributive formula

a(b - c) = ab - ac

$x^3(3x - 5) = \boxed{\bf{3x^4 - 5x^3}}$

You can use trigonometry specially the cos rule in this case. I can’t send the other pictures. But using the cos rule you can check whether the angle is 90
