Answer:

Step-by-step explanation:
=> Since it is an equilateral (Having all angles and all sides equal) triangle, so every angles will be equal to the other.
=> The sum of the measures of interior angles of triangle add up to 180 degrees.
So,
3x + 3x + 3x = 180
9x = 180
Divide both sides by 9
x = 20

QR is congruent to PS
So if QR is 17.7 PS is 17.7
Answer 3.) PS equals 17.7
A. v.kubus = s×s×s
= 6×6×6
= 216
b. v.kubus = s×s×s
= 5,6×5,6×5,6
= 175,616
c. v.kubus = s×s×s
= 34×34×34
=39304
X is less than or equal 18. I hope it helps
