Find the value of x
Answers
Answer:
27 degrees
Step-by-step explanation:
12: 180 = 3x - 17 + x + 40 + 2x - 5
180 = 6x + 18
180 - 18 = 6x
162 = 6x
x = 27 degrees
Answer:
Remember the Triangle Angle Sum theory which states that all angles of a triangle add up to 180˚. With this, make the following equation:
(3x-17) + (x + 40) + (2x - 5) = 180
Get rid of parenthesis
3x - 17 + x + 40 + 2x - 5 = 180
Group like terms:
3x + 2x + x + 40 - 17 - 5 = 180
Simplify
6x + 18 = 180
Subtract 18 from both sides.
6x + 18 - 18= 180 -18
6x= 162
Divide both sides by 6
6x/6= 162/6
x= 27

A. Find the complement of the angle shown.
B. Find the supplement of the angle shown.
Show all your work.
Answers
Answer:
Complement is 38
Supplement is 128
Step-by-step explanation:
Ok, so you know a complementary angle is 90 degrees and a supplementary angle is 180. To find the complement of the angle is another way of saying “make it add up to 90” You would show your work by writing “x + 52 = 90” to find the complement and “x + 52 = 180” I am assuming you know how to solve from here and that’s how I got the answer.

Step-by-step explanation:
One way we can find a percentage of two numbers is to divide, and then multiply our quotient by 100. In this case, the question is: What percent of 25 is 12? We will divide 12 by 25, which gives us 0.48. 0.48 x 100 is 48, which gives us our answer: 12 is 48% of 25.

Answers
Answer: hose Is raled to fill Ihe pool in 10 hours erhe To fill a pool, Barb uses two hosesThe first third hose that uses {ha slower to fill it in 5 hours. If Barb adds second hose is rated "long will it take to fill the pool?
Give Brainliest! Thanks.
It will take 10/3 hours to fill the pool when both the hoses will work together.
The first hose is rated to fill the pool in 10 hours.
This means, In one hour hose will fill 1/10th part of the pool.
The second hose is rated to fill the pool in 5 hours
This means, In one hour hose will fill 1/5th part of the pool.
What will be the total part of the pool to be filled?The total part of the pool to be filled will be 1.
Let us suppose both the hoses working together takes t hours to fill the pool
So, the first hose will fill the t/10th part of the pool.
The second hose will fill the t/5th part of the pool.
So, [tex]\frac{t}{10} +\frac{t}{5} =1[/tex]
15t =50
t=10/3
Therefore, It will take 10/3 hours to fill the pool when both the hoses will work together.
