Need help finding X and Y

X= 70º and Y= 60º

Step-by-step explanation:

Looing at the Triangles, those lines represent that the angles of the other side are equal.

In this case we have an Isosceles triangle and a Equilateral.

We got the angle of 55º and since it is Isosceles we get another 55º getting us 110º.

In a Triangle there is 180º so that would leave x as 70º.

Because there is one solid line for the smaller triangle, this states that it is a equilateral and thus makes y be 60º.

step-by-step explanation:

because i said it is

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
