Angle 2 and 4 is 67 degrees
You get this by adding 72 and 41 and subtracting it from 180
64/2=32-12=20 Barry has 20 butterflies left in his collection
The angle of elevation is = 70° and the distance the airplane travelled in the air is = 17,557ft
<h3>Calculation of the distance travelled</h3>
- To calculate the angle of elevation of the airplane
tan x° = opposite/adjacent
where opposite = 16,500 feet
adjacent = 6,000 ft
tan x° = 16,500 / 6,000
tan x° = 2.75
X = arctan ( 2.75)
X = 70°
- To calculate the distance the airplane travelled in the air Pythagorean Theorem is used.
C² = a² + b²
C² = 16,500² + 6,000²
C² = 272250000 + 36000000
C² = 308250000
C= √308250000
C= 17,557ft

11% or 3/9 should be right. Hope it helps :)
Well since there is 12 months in a year you would multiply 35 by 12, so the answer is 420
