Answer:
-32
Step-by-step explanation:
Please give me branliest!
In quadrant IV, cosine is positive and sine is negative. This means that
The cotangent is defined as the ratio between the cosine and sine:
So, we have the following equation:
Squaring both sides yields
The solution to this equation would be
But we know that the cosine has to be positive, so we have
And
Finally, the secant is the inverse of the cosine, so it's
Answer:
all of the above
Step-by-step explanation:
I woud make that fraction a decimal. 5/2= 2.5
It takes 2.5 seconds to cover 50 yards. We need to do y/x to find the rate, or yards/time.
50÷2.5= 20
The cheetah covers 20 yards every second. We can find how many sets of 20 yards are in 80 yards to find the number of seconds.
80÷20= 4 × 1 = 4
It would take 4 seconds for the cheetah to run 80 yards.
Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77
the 3 sides a + b + c = 199
b = a + 6
c = a + 19
substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58
then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77
