19). sin(a) = 35/37
cos(a) = 12/37
Third choice.
20).
tangent(20°) = 10/x
x = 10/tangent(20°) = 10/0.364 = 27.475
Rounded to the nearest tenth: x = 27.5
Answer:
(-9x+7)+(-6x-13)= -15x + -6
Step-by-step explanation:
-9x+-6x = -15x
7+-13=-6
therefore, -15x+-6 = (-9x+7)+(-6x-13)

Answer:
Question 5: y = 6.69 ft
Question 6: z = 12.52 in
Step-by-step explanation:
<u>Question 5</u>
In the right triangle shown, with respect to the angle given, y is the side that is "opposite" and the known side (15) is the "hypotenuse".
Note: The side opposite of right angle is the hypotenuse
Which trigonometric ratio relates "opposite" and "hypotenuse"? It is "SINE".
Let's setup the ratio and solve for y:
So,
y = 6.69 feet
<u>Question 6</u>
With relation to the angle given, we have the "adjacent" side and the "hypotenuse".
Which trigonometric ratio relates "adjacent" with "hypotenuse"?
<em>It is COSINE!</em>
<em />
We can set up a ratio as the previous question and solve for z:
So,
z = 12.52 inches
