Answer:
<h2>
m∠ABC = 30°</h2>
Step-by-step explanation:
m∠BAD = 0.5m∠BCD = 0.5•126° = 63°
The angles in quadriteral add to 360°, so:
m∠ABC + m∠BAC + m∠ACD + reflex m∠BCD = 360°
m∠ABC + 63° + 33° + (360° - 126°) = 360°
m∠ABC + 96° - 126° = 0
m∠ABC = 30°

17) 5ft</h3>
In order to do this problem you must use square roots. Basically the same number multiplied twice to get your answer. In this problem, 5 * 5 = 25.
<h3>
18) 10m</h3>
Since they are asking for the square root to the nearest whole unit, we must know that the √105 lies in between 10 and 11, since 10 * 10 = 100 and 11 * 11 = 121. 105 is closer to 100 than it is to 121 and therefore the answer is 10.
Don't forget your labels!!! (Feet and meters)
Answer:
400mph and 465 mph
Step-by-step explanation:
let the speed of first plane be x
speed of 2nd plane = x+65
dist travelled by first plane in 2 hrs = 2x
dist travelled by 2nd plane = 2(x+65)= 2x+130
when they meet, the sum of dist travelled by them is 1730
4x + 130 = 1730
4x = 1600
x = 400moh
x+65 = 465 mph
