Answer:
<u>30°</u>
Step-by-step explanation:
This right triangle has :
- right angle (90°)
- One angle of 60°
=========================================================
Solving :
We know the angle sum of a triangle is 180°.
⇒ x + 90° + 60° = 180°
⇒ x + 150° = 180°
⇒ x = <u>30°</u>
Step-by-step explanation:
| v − 455 | < 23
Writing this without absolute values:
-23 < v − 455 < 23
Solving for v:
432 < v < 478
In interval notation: (432, 478)
This interval is within the range of blue wavelengths, so the fireworks will be blue.
The answer is the top right one.
Each of the other answers is saying the same thing, just in different words, that the slope of the equation is 2. The top right is incorrect.
Answer:
y=5/16 - x/2
make y the subject of the formula and simplify afterwards
