1/2 is your answer. Hope that helps
The rule for angles in a triangle is that they all need to add up to 180°, so you can make the three expressions equal 180 and solve:
x + 10 + x + 2 + 9x - 8 = 180
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16
So your answer is 16
I hope this helps!
Answer:
A'(-1,-4)
B'(-5,-8)
C'(-5,-4)
D'(-4,-2)
Step-by-step explanation:
We have been given a graph of a quadrilateral and we are asked to find the coordinates of our quadrilateral after reflecting it across the x-axis.
We can see that coordinates of quadrilateral ABCD are:
A (-1,4),
B (-5,8),
C (-5,4),
D (-4,2).
Since we know that rule for reflecting an image across x-axis is . This means that y-coordinates of our given image will be negative.
So after reflecting our given quadrilateral across x-axis, coordinates will be:
The three angles of a triangle equal 180
Third angle = 180 - 31.8 - 89.8 = 58.4
Answer: 58.4
