As all humans know that the every angle of a square measures 90 degrees

so that
4t+20 = 90
4t=90-20=70
t=4.5


and
7f+6=90
7f=90-6=84
f=12


hope you got the idea

For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.

Therefore, we have the following equations:

[tex] 4t + 20 = 90

7f + 6 = 90
[/tex]

From these equations, we can clear the values of the unknowns.

For equation 1 we have:

[tex] 4t + 20 = 90

4t = 90 - 20

4t = 70
[/tex]

[tex] t = \frac{70}{4}

t = 17.5
[/tex]

For equation 2 we have:

[tex] 7f + 6 = 90

7f = 90 - 6

7f = 84
[/tex]

[tex] f = \frac{84}{7}

f = 12
[/tex]

Answer:

The values of t and f are given by:

[tex] t = 17.5

f = 12 [/tex]
