Find m∠A.<br> A. 32<br> B. 26<br> C. 27<br> D. 30

krok68 [10]

<h3>Answer: B. 26</h3>

============================================

Use law of cosines to find angle A

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

9^2 = 6^2 + 14^2 - 2*6*14*cos(A)

81 = 36 + 196 - 168*cos(A)

81 = 232 - 168*cos(A)

81 - 232 = -168*cos(A)

-151 = -168*cos(A)

-168*cos(A) = -151

cos(A) = (-151)/(-168)

cos(A) = 0.8988095

A = arccos(0.8988095)

A = 25.9979801

A = 26 degrees approximately

I don't understand this question, can you maybe reword it or make it easier to understand? There's no grammar so I can't understand.

Melissa put her cat, Herman, on a diet and kept track of his weight. At the end of 4 weeks, she recorded Herman's weight change

Sergio [31]

The cats weight change each week is $-1\frac{1}{8}$ ounces

<h3><u>Solution:</u></h3>

Given that, Melissa put her cat, Herman, on a diet and kept track of his weight.

At the end of 4 weeks, she recorded Herman's weight change as $-4\frac{1}{2}$ ounces.

She noticed that he had lost the same amount of weight each week.

We have to find what is Herman's weight change each week of the diet?

Now, let the weight lost per week be n ounces.

Then, in total he lost 4n ounces in 4 weeks

And we are given that, lost wait is $-4\frac{1}{2}$ ounces

$\begin{array}{l}{4 n=-(4 \frac{1}{2}) \text { ounces }} \\\\ {4 n=-(\frac{4 \times 2+1}{2})} \\\\ {4 n=-(\frac{9}{2})} \\\\ {n=-(\frac{9}{8})=-(\frac{8+1}{8})=-1 \frac{1}{8} \text { ounces }}\end{array}$

Here negative sign indicates cat is losing weight

Hence, the cats weight change each week is $-1\frac{1}{8}$ ounces

Answer:

BAE

Step-by-step explanation:

A quarter circle (angle BAD) will have a measure of 360°/4 = 90°. An angle of 105° will be larger than 1/4 circle. The only angle on the diagram larger than BAD is BAE.

The measure of angle BAE is 105°.
