I see two lines. The degree measure of any line is 180°.
4y + 5y = 180°
9y = 180°
y = 180°/9
y = 20
Answer:
We need to do difference so we can have how many numbers differ between the 2 numbers
Step-by-step explanation:
For example: 5-2=? We want to know what is the difference between the number which is 3 hope I explained it the best I can!!
Answer:
4833 m
Step-by-step explanation:
Given that her angle of elevation at the first recording is 47.3 at an altitude of 4900 m
We use Pythagoras Theorem to get this done
We can say that the opposite of the angle is the altitude, while the hypotenuse of the triangle, is the distance between herself and the top
Using the sine angle rule, we have
Sine 47.3 = 4900 / h
h = 4900 / sin 47.3
h = 4900 / 0.7349
h = 6668 m
This means that she was 6668 m away from the top of the mountain
She then moves 1000 m closer to the mountain top, this means that our h = 6668 - 1000
Using the same sine angle rule, we have
Sine 58.5 = o / 5668
o = 5668 * sine 58.5
o = 5668 * 0.8526
o = 4833 m
She is 4833 m above the sea level
To know for sure I’d need to see the bar graph. But with in the information present the answer would be 12.25% or 1/8
