Answer:
y = 70 degrees
x = 11
Step-by-step explanation:
The side opposite x + 2 is equivalent so they will both be equal to 13.
To get the meaning of x, simply subtract 2 from 13 giving you x = 11.
Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.
Hope this helps you :)
Answer:
39/4
Step-by-step explanation:
Step 1 - Setup
First, we set up the mixed number 9 3/4 with different colors, so it is easy to follow along:
9
3
4
Step 2 - Multiply
Next, we multiply the whole number by the denominator.
9 x 4 = 36
Step 3 - Add Numerator
Then, we add the numerator to the answer we got in Step 2.
36 + 3 = 39
Step 4 - Solution
Finally, to get the solution, we keep the original denominator and make the numerator the answer from Step 3. Thus, 9 3/4 as an improper fraction is:
39
4
the line that is parallel will be y = 1/2x
The geometrical relationships between the straight lines AB and CD is that they are parallel to each other
<h3>How to determine the relationship</h3>
It is important to note the following;
- A drawn from the origin and passes through point A (a , b), then the equation of OA = ax + by
- If a line is drawn from the origin and passes through point B (c , d), then the equation of OB = cx + dy
We find the equation of AB by subtracting OB from OA, thus AB = (c - a)x + (d - b)y
The slope of line AB =
⇒ OA= 2 x + 9 y
⇒ OA = 4 x + 8 y
⇒AB = OB - OA
⇒AB = (4 x + 8 y) - (2 x + 9 y)
⇒ AB = 4 x + 8 y - 2 x - 9 y
Collect like terms
⇒ AB = (4 x - 2 x) + (8 y - 9 y)
⇒AB = 2 x + -y
⇒ AB = 2 x - y
⇒ Coefficient of x = 2
⇒ Coefficient of y = -1
⇒ The slope of ab =
= 2
For CD
⇒ CD = 4 x - 2 y
⇒Coefficient of x = -4
⇒ Coefficient of y = -2
⇒The slope of cd =
= 2
Note that Parallel lines have same slopes
And Slope of ab = slope of cd
AB // CD
Therefore, the geometrical relationships between the straight lines AB and CD is that they are parallel to each other
