Answer:
Step-by-step explanation:
4 because as shown below. An equilateral triangle has 3 lines of symmetry.
P would then equal (-4,7) after the reflection
Don’t let R confuse you as it stands for Reflection. In this question you want to do a reflection across the y-axis.
The formula for reflection across the y-axis is (-x,y). In meaning as you cross the y-axis you y-value will always stay the same while your x-value with the opposite of what it is currently.
With that being said you want to plug in your values from point P to the formula which will leave you with (-4,7)
Divide 45 by 150 then multiply by 100:
45 / 150 = 0.3
0.3 x 100 = 30%
The answer is 30%
The numerator stays in the house and the denominator shows the power
