Answer:
![sin(\theta)=\frac{5}{13}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7B5%7D%7B13%7D)
Step-by-step explanation:
step 1
Find the hypotenuse of the right triangle with legs of 5 ft and 12 ft
Applying the Pythagoras Theorem
Let
d ----> the length of the hypotenuse
![d^{2}=12^2+5^2](https://tex.z-dn.net/?f=d%5E%7B2%7D%3D12%5E2%2B5%5E2)
![d^{2}=169](https://tex.z-dn.net/?f=d%5E%7B2%7D%3D169)
![d=13\ ft](https://tex.z-dn.net/?f=d%3D13%5C%20ft)
step 2
Find the sine of angle theta
Remember that
The sine of angle theta is equal to divide the opposite side of angle theta (5 feet) by the hypotenuse (13 feet)
![sin(\theta)=\frac{5}{13}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7B5%7D%7B13%7D)
Usually when you add big numbers together, you get a result of exponents involved :) answer for your question : 1.212154551 e^22
Answer:
hello and thank u for asking questions
the correct answers are...
A. is correct because an obtuse angle is an angle that measures over 90°
B. is incorrect because the acute angle is less than 90°
C. is correct because a reflex is "Reflex angles are angles measuring greater than 180 degrees and less than 360 degrees. The measure of a reflex angle is added to an acute or obtuse angle to make a full 360 degree circle"
D. is incorrect because if it is less than 2 but greater than 4 that does not make any sence
hopes this help pls mark brainiest and have a great and wonderful rest of your day
Answer:
Your answer is 35 Minutes
Step-by-step explanation:
105-70 = 35
Answer:
(0.4, -57.9)
Step-by-step explanation:
y = 3x³ + 12x² - 10x - 56
dy/dx = 9x² + 24x - 10 = 0
x = [-24 +/- sqrt(24² - 4(9)(-10))]/(2×9)
x = -3.033006505, 0.3663398379
d²y/dx² = 18x + 24
For minima, d²y/dx² > 0 which is at x = 0.3663398379
y = 3(0.3663398379)³ + 12(0.3663398379)² - 10(0.3663398379) - 56
y = -57.90544608
