Answer:
45°
Step-by-step explanation:
three angles in a triangle sum up to 180
90° + a + a = 180°
90° + 2a = 180°
2a = 180°-90°
2a = 90°
a = 45°
Answer:
The correct option is;
y = arcsinx and y = arctanx
Step-by-step explanation:
The given options are;
1) y = arcsinx and y = arccosx
Here, we have at the origin, where x = 0, arccosx ≈ 1.57 while arcsinx = 0
Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin
2) y = arccosxy and y = arctanx
Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical
3) y = arctanx and y = arccotx
Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical
4) y = arcsinx and y = arctanx
Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.
Answer:

Step-by-step explanation:
f=v+at
It requires you to make a the subject of the formula
f-v=at
Dividing both sides by t then

Therefore, the equivalent for a is
