true

Step-by-step explanation:

this is correct

Answer from: imanim3851

False

Step-by-step explanation:

Dilated triangles must have the same angle measures, but different side lengths. Let’s see if it’s possible for the two triangles to have the same angle measures for all 3 angles.

X’Y’Z’ has angles 27 and 86 degrees. The sum of the angles in a triangle must add up to 180:

180 - (27+86) = 67.

The three angles of X’Y’Z’ are 67, 86, and 27! So those aren’t the same as triangle XYZ’s angles.

Therefore these two triangles are not a dilation of one another, the ratios are not the same, and they do not have 3 pairs of congruent angles.

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph
