The angle of the plane when it rose from the ground is 64.8 degrees

<h3>Application of trigonometry identity</h3>

Given the following parameters from the question

Altitude of the airplane H =  500m

Horizontal distance from airport "d"  = 235

Required

angle of elevation

According to the trigonometry identity

tan x = opposite/adjacent

tan x = H/d
tan x = 500/235

tan x = 2.1277

x = arctan(2.1277)

x = 64.8 degrees

The angle of the plane when it rose from the ground is 64.8 degrees

an actor gains 20pounds for a part and then losses 15 pounds during the filming of the movie to go along with the story.who do y
guajiro [1.7K]
Let the actor's initial weight be 'x'

He is then gaining 20 pounds. The clue is in the word 'gaining' as it means 'increasing' or in Mathematics can be related as 'plus'

The expression is: x+20

He then loses 15 pounds. The clue is in the word 'losses' as it means 15 pounds is to be subtracted from the last value

Last value is x + 20
The weight now is x + 20 - 15 = x + 5

Draw a number line to<br><br> represent the inequality.<br><br> y s 23
Mkey [24]

Answer:

The number lines are shown below.

Step-by-step explanation:

In the given problem the sign of inequality is missing.

We know, that there are 4 signs of inequality ">", "<", "≥" and "≤".

The possible inequalityes are

y>23

y

y\geq 23

y\leq 23

In y>23, all points on the right side of 23 are included in the solution set.

In y, all points on the left side of 23 are included in the solution set.

In y\geq 23, 23 and all points on the right side of 23 are included in the solution set.

In y\leq 23, 23 all points on the left side of 23 are included in the solution set.

14) 15 : 1

<u>Ratio = Number of event 1 : Number of event 2</u> (in same unit, if necessary)

<u>10</u>

Girls preferring orange juice : Boys preferring orange juice

50 : 48 (Divide by 2 on both sides)

25 : 24

<u>11</u>

Boys preferring orange juice : Boys preferring grapefruit juice

24 : 5

Remember :

  • <u>1 minute = 60 seconds</u>
  • <u>1 week = 7 days</u>
  • <u>1 hour = 60 minutes</u>

<u />

<u>12</u>

3 minutes : 25 seconds

3 × 60 : 25 (Divide by 5 on both sides)

3 × 12 : 5

36 : 5

<u>13</u>

2 weeks : 6 days

2 × 7 : 6 (Divide by 2 on both sides)
