An angle measures 111.4° more than the measure of its supplementary angle. What is the measure of each angle?
fomenos

The measure of the supplementary angles are 34.3 and 145.7 degrees.

<h3>What are supplementary angles?</h3>

Supplementary angles are those angles that sum up to 180 degrees.

In other words, two angles are Supplementary when they add up to 180 degrees.

Therefore, the angles measures 111.4° more than the measure of it's supplementary angle.

Hence,

let

x = measure of the other angle

x + x + 111.4 = 180

2x + 111.4 = 180

subtract 111.4 from both sides

2x + 111.4 - 111.4 = 180 - 111.4

2x = 68.6

divide both sides by 2

x = 68.6 / 2

x = 34.3

Other angle  = 34.3 + 111.4 = 145.7°

Therefore, the measure of the supplementary angles are 34.3 and 145.7 degrees.

The length of a rectangular garden is 5x+5
REY [17]

Answer:

4x+14

Step-by-step explanation:

we know that in a rectangle, 2 sides are equal to one another (opposite sides), and the other 2 are equal to each other.

so,

2(5x+5) for the first 2 sides. you'd get 10x+10

2(2-3x) for the other two sides. you'd get -6x+4

add them up, and you'd get 4x+14

I just need help. So, with this, since it’s 6.633 then would it just go back to 6.63 or to 6.60?
Brums [2.3K]
When you round, if the number you are rounding is more than 0, it will never be rounded down to 0. So 6.63 can never be rounded to 6.60 since 3 is more than 0.
In order to round the hundredths, you need to look at the thousandths. 
The thousandths in 6.633 is the second 3.
Since 3 is less than 5, the first 3 will remain the same.
The correct answer is 6.63

hope this helps =)
