To find the interior of Y
Y = 180 - 135
Y = 45
The interior of Z is 49 because the angles are mirrored to each other
then, to find x,
X = 180 - 45 - 49
X = 86
so your answer should be 86.
Answer:
5
Step-by-step explanation:
Distance=speed times time
distance/time=speed
distance=30km
time=2.5hr
distance/time=30km/2.5hr=60km/5hr=12km/1hr=12km/hr
her speed is 12km per hour
Answer:
14/27 feet
Step-by-step explanation:
2 1/3 feet : 4 1/2 feet
= 7/3 : 9/2
= 7/3 ÷ 9/2
= 7/3 × 2/9
= (7*2)/(3*9)
= 14/27 feet
2 1/3 feet : 4 1/2 feet = 14/27 feet
Answer:
4) 2(x - 3)^2 + 2(y + 5)^2 = 96.
Step-by-step explanation:
2x^2 – 12x + 2y^2 + 20y – 28 = 0
2(x^2 – 6) + 2(y^2 + 10y) = 28
2 ( (x - 3)^2 - 9)) + 2((y + 5)^2 - 25) = 28
2(x - 3)^2 - 18 + 2(y + 5)^2 - 50 = 28
2(x - 3)^2 + 2(y + 5)^2 = 28 + 18 + 50
2(x - 3)^2 + 2(y + 5)^2 = 96
