Find the value of x and y
Answer:
x = 80, y = 122
Step-by-step explanation:
I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).
3/4x+2/5x-2=90°,
23/20x - 2=90°,
23/20x = 92°,
92/(23/20)
20/(1/4)
20(4)
= 80.
Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.
180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122
If you have a two-step word problem, is it normal to do 5 steps?
My teacher is making my class to "two-step expressions" but he says to do 5 steps.
Is that normal because it says in its name 2 steps?

it would be 2
1 2/5 - (-3/5) = 2
△LMN and △NOP similar right triangles. The coordinates of all the vertices are integers.
The slope of LN¯¯¯¯¯ is equal to the slope of NP¯¯¯¯¯¯. This because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for LN¯¯¯¯¯ as for NP¯¯¯¯¯¯
The relationship between the slope of LN¯¯¯¯¯ and the slope of NP¯¯¯¯¯¯ cannot be determined, because the triangles are congruent.
The slope of LN¯¯¯¯¯ is greater than the slope of NP¯¯¯¯¯¯. This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for LN¯¯¯¯¯ than for NP¯¯¯¯¯¯.
The slope of LN¯¯¯¯¯ is less than the slope of NP¯¯¯¯¯¯. This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for LN¯¯¯¯¯ than for NP¯¯¯¯¯¯.
