*BEST ANSWER WILL BE MARKED BRAINLIEST*<br><br> MNOP is a square. what are the value of t and f?
igomit [66]

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:

4t + 20 = 90\\7f + 6 = 90

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

For equation 1 we have:

4t + 20 = 90\\4t = 90 - 20\\4t = 70

t = \frac{70}{4}\\t = 17.5

For equation 2 we have:

7f + 6 = 90\\7f = 90 - 6\\7f = 84

f = \frac{84}{7}\\f = 12

Answer:

The values of t and f are given by:

t = 17.5\\f = 12

pogonyaev

Answer:

I'm assuming we need to find the number of minute she as used. to do that we can right an inequality with m being the number of minutes

18+0.06m≥88.56

we then just solve this like we would with any other algebra equation, First we subtract 18 from both sides.

0.06m≥70.56

Then we dives by 0.06

m≥1176

Rania has used at least 1176 minutes
