Answer:

45 degrees

Step-by-step explanation:

∠1 and ∠4 are on a straight line. Therefore, they are supplementary and add to 180 degrees.

∠1+∠4=180

We know that the m∠1 is 135 degrees. We can substitute 135 in for ∠1.

135+∠4=180

Now we have to solve for ∠4. To do this, we need to get ∠4 by itself. 135 is being added on to ∠4. To undo this, subtract 135 from both sides, because subtraction is the opposite of addition.

135-135+∠4=180-135

∠4=180-135

∠4=45

The measure of ∠4 is 45 degrees.

Hi could somebody help me

alexandr402 [8]

Assuming both vertical lines are parallel and assuming I'm supposed to find all the unmarked angles...

Angle C:

Supplementary Angles.

x+36=180

180-36=x

x=144

Angle B:

Corresponding Angles.

Angle B ≅ Angle C

144

Angle A:

360 degrees in a quadrilateral

36+144+81+x=360

261+x=360

x = 99

The symbol ₁₂P₉ represents the permutations of 9 quantities out of 12.
By definition,
$_{12}P_{9} = \frac{12!}{(12-9)!} = \frac{12!}{3!}$

From the calculator,
12! = 479,001,600
3! = 6

Therefore
₁₂P₉ = 479001600/6 = 79,833,600

Answer: 79,833,600
