In triangle ABC, a = 9, c = 5, and angle B = 120°. Find the measure of angle A to the nearest degree. Show your work.

slamgirl [31]

<u>Answer:</u>

Angle A = 39°

<u>Step-by-step explanation:</u>

We are given that there is a triangle ABC where a = 9, c = 5 and angle B = 120° and we are to find the measure of angle A.

But first we need to find the side b using the law of cosine:

$b^2 = a^2 + c^2- 2a*c*cos(120)$

$b^2 = 81 + 25 - 2*9*5*(-0.5)$

$b=\sqrt{151}$

Now finding angle A using law of cosine:

$cos(A) = \frac{b^2+c^2-a^2}{2b*c}$

$cos(A) = \frac{151+25-81}{2*12.29*5}$

$cos A=0.7730$

$A=39.38$

Therefore, the measure of angle A = 39°.

Use a calculator to solve for theta in the given interval

Allushta [10]

Answer:

d. $1.82\: or\:4.46$

Step-by-step explanation:

The given trigonometric equation is;

$\sec \theta=-4.0545$

Recall that;

$\cos \theta=\frac{1}{\sec \theta}$

$\implies \cos \theta=\frac{1}{-4.0545}$

$\implies \cos \theta=-0.2466$

The cosine function is negative in the second and third quadrant.

$\theta=\pi-\cos^{-1}(0.2466)\: or\:\pi+\cos^{-1}(0.2466)$

$\theta=1.82\: or\:4.46$
