Complementary angles are 2 angles who add up to 90 degrees. Every one of the angles adds up to 90 degrees, so the assignment is asking you to find the missing number that makes the angles add up to 90.

Example: The first angle on your pager shows 45 and and a question mark. Ask yourself, what number + 45 = 90? The answer is 45. So, take the number of each angle they give you, and subtract it from 90. ( 90 - 45 ) and you have solved what the missing number ( ? ) is. Hope I helped!

Subtract the degrees shown by 90 since it is a right angle, which mean sit is at 90 degrees. so like for the 1st one, subtract 45 from 90. any questions?

Answer:

Option C

Step-by-step explanation:

From the number line given in the picture,

Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.

Therefore, number line represents a ≤ 6

3a ≤ 3(6)

3a ≤ 18

3a - 11 ≤ 18 - 11

3a - 11 ≤ 7

Therefore, Option C is the correct option.

Plsss Help me plsssssssssssss
Mazyrski [523]

Answer:

If, a = 2 and b = 3

<h3>Jada</h3><h3>10a + 1b = 7a + 5b  - 3a + 4b \\ 10(2) + 1(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 20 + 3 = 14 + 15 - 6 + 12 \\ 23 = 35 \\</h3>

It's not equivalent.

<h3>Diego</h3><h3>4a + 9b = 7a + 5b - 3a + 4b \\ 4(2) + 9(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 8 + 27 = 14 + 15 - 6 + 12 \\ 35 = 35 \\</h3>

It's equivalent.

The correct equation is 4a + 9b.
