In ABC, angle C is a right angle. Which statement must be true
Answer:
a
Step-by-step explanation:
a because the the sin is opposite divided by hypotenuse and the opposite of a is 12 and the hypotenuse is 13 so sin a would be 12/13
this is equals to the cosine of b because cos is adjacent/hypotenuse and the adjacent of b is 12 and the hypotenuse is 13 so cos b would be 12/13
hope this helps :)

In order to make a safe parachute landing from a mountain top, you must be at least 9,000 feet in the air. At the top of Mount Montgomery, the angle of depression is 19 degrees looking diagonally down at a landing zone that is 16000 feet away from the middle of the mountain. Determine if it is safe to use a parachute from the top of this mountain.
Answer:
Send me a picture I can help u
Answer:
Step-by-step explanation:
tan19=h/16000
h=16000tan19
h=5509.24ft
So it is less than 9000ft and is unsafe to use the parachute.

35.5
30.8
27.3
32.1
23.8
29.9
Find the mean temperature.
Answer:
29.9 °F
Step-by-step explanation:
The formular for mean is given as;
Mean = Sum of Terms / Number of terms
Number of terms = 6
Sum of terms = 35.5 + 30.8 + 27.3 + 32.1 + 23.8 + 29.9 = 179.4
Mean = 179.4 / 6 = 29.9

what Is the answer to 1/6 + 2/3
Answer:
5/6
Step-by-step explanation:
When adding fractions, you must ensure the denominator is the same in both fractions.
In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.
When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.
2/3 × 2/2 = (2×2)/(3×2) = 4/6
Replace 2/3 with its equivalent 4/6.
Now you will add the numerators together.
1/6 + 4/6 = (1+4)/6 = 5/6
Your final answer is 5/6
Answer:
5/6
Step-by-step explanation:
2/3--> 4/6 (GCF)
4/6+1/6=5/6

The larger angle <K, has a measure of 120 degrees.
Step-by-step explanation:
So, a supplementary angle are two or more angles that combine to form a 180 degree straight line. So here, we need to set up an algebra equation.
2x = the larger angle (because it's two times the smaller angle)
x = the smaller angle
So then, you need to set both equal to 180 degrees, since combine they equal 180 degrees
2x + x = 180
3x = 180
x = 60
Using basic algebra, we see that the smaller angle is 60 degrees, but wee need to find the larger angle. Remember, we represented the larger angle as 2x.
2 time 60 is 120, so the larger angle is 120 degrees
Hope that helps :)
