Answer:
True
Step-by-step explanation:
Any two points on the line together with the third point not on the line will define exactly one plane.
ANSWER
45 green bands
EXPLANATION
The ratio of red hair bands to green hair bands is
5 : 9
The total ratio is:
If there are a total of 70 hair bands,
Then the number of green bands
Simplify
Multiply
Therefore, there are 45 green bands.
Answer: -2x + 5y = 8
Step-by-step explanation:
Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y
Substitute the values of x and y from the given coordinate (6,4) to find the new constant, b, the y-intercept.
-2x + 5y = b
-2(6) + 5(4) = b
-12 + 20 = b
8 = b
Rewrite the original equation substituting the new b for the original -15
-2x + 5y = 8
6 because when you add four plus two or two plus four you get six
Answer:
<A = 124
Step-by-step explanation:
Remark
This figure has 7 angles. Therefore it can have 5 lines drawn from 1 vertex to all the other vertexes. That gives you 5 triangles. See the diagram below to see the result of what I have just described. The sum total of all the interior angles is 5 * 180 = 900
Equation
Add the seven given angles from your figure to equal 900
(9x - 2) + (10x + 2) + 165 + 100 + (5x + 83) + (12x + 18) + 138 = 900
Solution
Now add all the like terms on the left together.
- Terms Containing "x"s: 9x + 10x + 5x +12x = 36x
- Terms not containing "x"s: -2 + 2 + 165 + 100 + 83 + 18+ 138 = 504
So this simplifies to
36x + 504 = 900 Subtract 504 from both sides
36x + 504 - 504 = 900 - 503 Do the subtraction
36x = 396 Divide by 36 on both sides
x = 396/36 Do the division
x = 14
Answer
But you want angle A.
<A = 9x - 2 = 9*14 - 2 = 126 - 2 = 124
