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

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
