Find the value of the variable of Y

y=5

Step-by-step explanation:

Since the two triangles are congruent to each other. Angles R and X are congruent to each other.

Set the equations to each other.

4y - 10 = 3y+5

1.) Add 10 to both sides

4y= 3y +15

2.) Subtract 3y to both sides

3y=15

3.) Divide by 3 to get y by itself

y=5

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
