Answer:
∠P = 39º
∠Q=120º
∠R = 21º
Step-by-step explanation:
m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)
2x-3+6x-6+x=180º (substitution)
9x-9=180º (algebra)
9x=189º (algebra)
x=21º (algebra) (this is ∠R)
(2x-3)=39º (algebra) (this is ∠P)
6x-6=120º (algebra) (this is ∠Q)
3 ft in a yard,
multiply that by 18 for 18 yards
you get 54
Answer:
Step-by-step explanation:
if you take the diameter of a circle and put it around the circumference you will need to have 3 and a bit more (pi=3.14) of diameters to cover the whole circumference.
C = pi*d = 3.14 * 7 = 21.98 feet
The average for all of the 6 tests is 93.5
5/7 * 1/9 = ?
(5 * 1) / (7 * 9) = 5 / 63
Answer: 5/63 or 0.079
