Answer: the expression is

A = Sin^-1(D/bc)

Step-by-step explanation:

The formula for determining the area of a triangle is expressed as

Area = bcSinA

Where b and c are the length of each side of the triangle. Angle A is the given angle corresponding to side a.

The area of the given triangle is D. It means that

D = bcSinA

Therefore, the expression that can be used to find the measure of angle A would be

D = bcSinA

Dividing both sides of the equation by bc, it becomes

D/bc = bcSinA/bc

SinA = D/bc

Taking inverse of sine of both sides of the equation, it becomes

A = Sin^-1(D/bc)

<h2>Answer with explanation:</h2>

Given : Sample size : n = 36

Significance level for 90% confidence : $\alpha: 1-0.9=0.1$

Sample mean : $\overline{x}=0.60$

Standard deviation : $\sigma=0.08$

By using standard normal table for t-values,

Critical t-value : $t_{(n-1, \alpha/2)}=t_{(35,\ 0.05)}=1.690$

Thus, the correct value of t to construct a 90% confidence interval for the true mean percentage of cacao : $t_{(35,\ 0.05)}=1.690$

Confidence interval for population mean :

$\overline{x}\pm t_{(n-1, \alpha/2)}\dfrac{\sigma}{\sqrt{n}}\\\\=0.60\pm(1.69)\dfrac{0.08}{\sqrt{36}}\\\\=0.60\pm0.0225333333333\\\\\approx0.60\pm0.023\\\\=(0.60-0.023,\ 0.60+0.023)=(0.577,\ 0.623)$

Hence, A is the correct answer .

Really confused on how to approach this problem.

kkurt [141]

Step-by-step explanation:

For this Q, you should draw a triangle to help you with the values.

cos x =

$\frac{ \sqrt{2} }{2}$

csc x =

$\frac{2}{ \sqrt{2} }$

tan x = sin x/ cos x

= 1

cot x = 1

sec x =

$\frac{ \sqrt{2} }{2}$

x = 45 degrees
