Use the 30-60-90 triangle.
Tan is opposite over adjacent.
Square roots cannot be on the bottom.
The bottom cancel out the square root bar.
Your answer is:
(It's best to memorize the 30-60-90 and the 45-45-90 triangles during trigonometry. It helps a lot.)
Hope this helps!

The point P could be located in quadrant I, quadrant IV and the x-axis
<h3>How to determine the quadrant?</h3>
The coordinate of point P is given as:
P = (a, b)
Where a is positive
When a is positive, then the likely locations of P are:
- On the x-axis, when b = 0
- In quadrant I, when b is positive
- In quadrant IV, when b is negative
Hence, point P could be located in quadrant I, quadrant IV and the x-axis

Answer:
The 90% confidence interval for the difference in mean (μ₁ - μ₂) for the two bakeries is; (<u>49</u>) < μ₁ - μ₂ < (<u>289)</u>
Step-by-step explanation:
The given data are;
Bakery A
<em> </em>= 1,880 cal
s₁ = 148 cal
n₁ = 10
Bakery B
<em> </em>= 1,711 cal
s₂ = 192 cal
n₂ = 10
df = n₁ + n₂ - 2
∴ df = 10 + 18 - 2 = 26
From the t-table, we have, for two tails, 
= 1.706
≈ 178
Therefore, we get;
Which gives;
Therefore, by rounding to the nearest integer, we have;
The 90% C.I. ≈ 49 < μ₁ - μ₂ < 289
