Answer:
-5/13
Step-by-step explanation:
sin theta = opp / hyp
sin theta = -12 /13
we can find the adj side by using the pythagorean theorem
adj^2 + opp ^2 = hyp^2
adj^2 +(-12)^2 = 13^2
adj^2 +144 =169
adj^2 = 169-144
adj^2 = 25
Taking the square root of each side
adj = ±5
We know that it has to be negative since it is in the third quad
adj = -5
cos theta = adj / hyp
cos theta = -5/13
Answer is Choice A - 1.
1 times 2 is 2, and 2 + 8 is 10.
Answer:
6:50
Step-by-step explanation:
The bell that rings every 10 min will ring at 6:00, 6:10, 6:20,6:30, 6:40, 6:50
The bell that rings every 25 min will ring at 6:00, 6:25, and 6:50
Answer:
8 + 13t
Step-by-step explanation:
Since 19t and 6t have the same variables
9a-5x
step by step explanation:
you can only add and subtract numbers that have the same variables.
12a and 3a are related because there variable is both a.
when u subtract 12a-3a you get the answer of 9a using subtraction.
7x and -2x are the second pair of related terms because they also have the same variable (x)
7x-2x is 5x using subtraction.
put the expression together:
9a-5x
hope this helps!
give me brainliest if it did plz
