Q # 6 please help to resolve
Rus_ich [418]
The numbers of choices in each category are multiplied together. We assume the order of paint choices matters: using color 1 in area A and color 2 in area B is not the same as using color 2 in area A and color 1 in area B.

P(7,2)*4*3*2 = 42*4*3*2 = 1008 ways

_____
P(n, k) = n!/(n-k)!
P(7, 2) = 7*6 = 42

HELP PLEASE I WILL GIVE 100 POINTS TO WHOEVER GIVES ME THE RIGHT ANSWER​
Dovator [93]

Answer:

44°

Step-by-step explanation:

Note that the square in located to the left of the two given intersecting lines denotes that it is a right angle, in which the measurements is 90°.

This means that:

∠α + ∠β = 90°

Let:

m∠α = x

m∠β = 46°

Plug in the corresponding numbers and variable to the given terms:

x + 46 = 90

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 46 from both sides:

x + 46 (-46) = 90 (-46)

x = 90 - 46

x = 44

x = 44° is your answer.
