Find the value of p that makes quadrilateral QRST a parallelogram.

1 answer:

7 0

P= 31

EXPLANATION :opposite sides of a parallelogram are congruent so angles R & S should equal to 180 degrees when you add them and so on for angles Q & T

ANGLES R & S :
2p+3p+25=180
5p+25=180
5p=180-25
5p=155
p=31

ANGLES Q & T
p+87+5p-93=180
6p-6=180
6p=180+6
6p=186
p=31

MATH CHECK:
2(31)+3(31)+25+(31)+87+5(31)-93=360
62+93+25+31+87+155-93=360
453-93=360
360=360

Answer: 340 students

Step-by-step explanation:

The number of students walking to school is 119 and this is 35% of the total number of students.

Assume the total number is denoted by "x".

That would mean that the following formula captures the situation:

119 = 35% * x

119 = 0.35x

x = 119/ 0.35

= 340 students
