If Angle 2 Is 45 Degrees, What Is The Measurement Of Angle 4?

Answers

Answer 1

Answer:

angle 4 = angle 2{opposite angles are equal} =45 degrees

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Angle 4 is an exterior angle which corresponds to the remote interior angles of 33 degrees and 75 degrees. Through the remote interior angle theorem, we can add the remote interior angles to get the exterior angle So we simply add 33 and 75 to get 33+75 = 108 If you chose not to use this theorem, then you can find angle three by using the fact that all three angles of the triangle must add to 180 degrees. So, 33+75+(angle 3) = 180 108+(angle 3) = 180 108+(angle 3) - 108 = 180 - 108 angle 3 = 72 degrees Then use the fact that angle 3 and angle 4 are supplementary (angle 3) + (angle 4) = 180 72 + (angle 4) = 180 72 + (angle 4) - 72 = 180 - 72 angle 4 = 108 degrees either way, we get the same answ

Answer:

g < 4

Step-by-step explanation:

Let's start with what his goal is. He wants to stay UNDER $65 per month so we will use the "<" symbol....

He also already has to pay $53 per month just for the plan, so we will subtract the total budget per month $65 - $53 = $12 left for extra gigabytes.

We have only $12 left to use for the extra gigabytes he wants to use.

We know that each gigabyte is $3 so it makes sense to say "3 times g" represents our situation, or "3g" and our budget is now technically $12.

(g = amount of gigabytes...)

We will solve for g

$3g < $123g/3 < 12/3g < 4

g < 4 hope it helps can I get brainlest please

Greatest common factor(GCF) of 90 & 45

Answers

Answer:

the answer is 45 for 90 &45

Answer:

The GCF is 45

Step-by-step explanation:

Step 1:  Find the prime factorization of each number

Prime Factorization of 90:  2 * 3 * 3 * 5

Prime Factorization of 45:  3 * 3 * 5

Step 2:  Multiply the numbers that they have in common

Both numbers have 3, 3, and 5 in common.  

So we just multiply them:  3 * 3 * 5 = 45

Therefore, the GCF of 90 and 45 is:  45

Answer: The GCF is 45
