80
Step-by-step explanation:
It's a 180 angle
The answer is 6/49 just multiply them. Negatives cancel each other.
Answer:
2 * cos(11t/2) * sin(3t/2)
Explanation:
To answer this question, we will simply use the formula relating the difference between the sines as follows:
sin A - sin B = 2 * cos[(A+B)/2] * sin [(A-B)/2]
Now, we have:
A = 7t
B = 4t
Substitute with the givens in the formula as follows:
sin 7t - sin 4t = 2 * cos[(7+4)/2] * sin [(7-4)/2]
sin 7t - sin 4t = 2 * cos[11t/2] * sin [3t/2]
Hope this helps :)
This is a Pythagorean theorem problem. the ladder is 12 from the building and needs to teach 14 ft up. the length of the ladder it's the hypotenuse
12²+14²=c²
144+196=c²
340=c²
c=√340 or about 18.5 ft
