First, we need to understand that these two triangles are
similar.
we know this because their lines (the arrows) prove they are the same direction. A similar triangle does
NOT mean they are proportional,
they are just similar by ratio.
Lets call the triangle on the left ABC and the triangle on the right A'B'C'.
I will attach an image of the labels.
Because they are similar triangles, angle A is the same as angle A'. Angle B is the same as angle B', angle C is the same as angle C'.
Based on that information, we know xº is = 65º. We know that the interior angles add up to 180º. So for triangle A'B'C', we can do 180º-40º-65º which is 70º. This means angle C' is 70º.
Now the important part is getting yº. A line is 180º. That means that 180º-70º=yº which is 110º.
If you do not understand anything, please let me know and I will try to teach you.
Answer:
A(3,6)
B(2,3)
C(4,2)
D(6,8)
E(8,4)
A=(-1,-1) B=(1,3)C=(2,5)D=(-2,-3)E=(3,7)
Answer:
30°
Step-by-step explanation:
53°+97°+x = 180°
The sum of three angles must equal 180°
Solve the equation.
150°+x = 180°
x = 180°-150°
x = 30°
Therefore, x = 30°
The solution to the given inequality is x < 9
<h3>What are inequality</h3>
Inequality are expressions not separated by an equal sign, Given the inequality
5x + 15< 60
Subtract 15 from both sides
5x < 60 - 15
5x < 45
Divide both sides by 5
5x/5 < 45/5
x < 9
The number line that describes the solution is attached
