Please help me with this question

Answer:

<h3>• y is 10.9</h3><h3>• theta is 65.4°</h3><h3>• Alpha is 24.64°</h3><h3>• sin theta is 10.9/12</h3><h3>• COS theta is 5/12</h3><h3>• tan theta is 10.9/5</h3><h3>• csc theta is 12/10.9</h3><h3>• ces is 12/5</h3><h3>• cot theta is 5/10.9</h3>

Step-by-step explanation:

<h3>Solution 1</h3>

Using the Pythagorean theorem

c²= a² + b², where c is the hypotenuse , a And b are the sides.

12² = y² + 5²

144 = y² + 25

144 - 25 = y²

√119 = √y²

10.9 = y

<h3>Solution 2</h3>

Using SOH-CAH-TOA

COS theta = Adjacent/Hypothesis

COS theta = 5/12

COS theta = 0.417

theta = COS-1 0.417

theta = 65.4°

<h3>theta is 65.4°</h3>

<h3>Solution 3</h3>

We are dealing with right triangle and it sum is 90.

To find Alpha subtract theta for 90

Alpha = 90 - 65.4 = 24.64°

<h3>Therefore Alpha is 24.64°</h3>

<h3>Solution 4</h3>

Using SOH-CAH-TOA

sin theta = opposite/ hypotenuse

sin theta = 10.9/12

<h3>sin theta is 10.9/12</h3>

<h3>Solution 5</h3>

Using SOH-CAH-TOA

COS theta = Adjacent/Hypothesis

COS theta = 5/12

<h3>COS theta is 5/12</h3>

<h3>Solution 6</h3>

Using SOH-CAH-TOA

tan theta = opposite/adjacent

tan theta = 10.9/5

<h3>tan theta is 10.9/5</h3>

<h3>Solution 7</h3>

csc theta is the reciprocal of sin theta

csc theta = 12/10.9

<h3>csc theta is 12/10.9</h3>

<h3>solution 8</h3>

ces theta is the reciprocal of COS theta.

ces theta = 12/5

<h3>Solution 9 </h3>

cot theta is the reciprocal of tan theta

cot theta = 5/ 10.9

<h3>cot theta is 5/10.9</h3>

Miss Angelino made 2 pans of lasagna and cut each pan into twelfths. Her family ate 1 1/12 pans of lasagna for dinner. How many

Jlenok [28]

1/2 because, if you have a total of 2 and you take away (or subtract in other words) 1 1/2 which is what they ate you get 1/2.

2= 2/1+ 4/2
4/2-1/2=1/2

- has to be solved and put as an inequality

8_murik_8 [283]

Answer:

(98+89+88+x)/5 > 92

366+x/ 5 > 92

x/5 + 73.2 > 92

x/5 > 18.8

x > 94

The lowest score that you can make and have a 92 average is a 94. Hope this helps!
