By <em>trigonometric</em> functions we find that the measure of angle A is approximately 0.12π radians.

<h3>How to determine the missing angle in a right triangle</h3>

In this question we have a <em>right</em> triangle, of which the length of two sides are known (AB, BC). We can know the measure of angle A by <em>trigonometric</em> functions:

$\tan A = \frac{BC}{AC}$

$\tan A = \frac{2}{5}$

A ≈ 0.12π radians

Answer:

"Dominic lived in Spain for 13 months and Columbia for 7 months."

Step-by-step explanation:

let months stayed in spain be "s" and months stayed in columbia be "c"

We can write 2 equations.

Since, lived in Spain and Columbia for a total of 20 months, we can write:

s + c = 20

Also, since 120 words per month in Spain and 150 words per month in Columbia for a total of 2610 new words, we can write:

120s + 150c=2610

Solving first for s:

s = 20 - c

Putting in 2nd and solving:

120(20 - c) + 150c = 2610

2400 - 120c + 150c = 2610

30c = 210

c = 7

Now,

s = 20 - c = 20 - 7 = 13

"Dominic lived in Spain for 13 months and Columbia for 7 months."

How do I work this out

Iteru [2.4K]

If the track is 10km long, and X travels at 40 km/h, it will take 1 hour to do 4 laps. this means that car X will do one lap in 15 minutes. Y travels at 30 km/h, which means it will do 3 laps in 1 hour, meaning that car X will do 1 lap in 20 minutes.

X- 15, 30, 45, 60
Y-20, 40, 60

Therefore, after an hour, they will pass again.

Terri played 70 tournament chess games during the school year and won 49 of them. What is her win-to-loss ratio?

Scilla [17]

Alright so the answer would be letter B, because

win-to-loss

49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)

Now you must simplify your answer

7 is the greatest common factor (GCF) of both 49 and 21

Now divide both 49 and 21 by 7 to get

7 to 3
