<span>sin 90° = 1
</span>
cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
You have to plug them in to see each solution, so the answers that apply would be 65 and 66 all the other answers are less than or equal to 8
Answer:
3/14
Step-by-step explanation:
1st subtract the y's
the subtract the x's in the same order
-9 - 5 = -14
put the first result over the second
-3/-14 = 3/14
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
2y + 8 = 2 • (y + 4)
Equation at the end of step 2 :
(0 - (4 • (4y - 10))) + 6 • (y + 4)
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
4y - 10 = 2 • (2y - 5)
Equation at the end of step 4 :
(0 - 8 • (2y - 5)) + 6 • (y + 4)
Step 5 :
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
64 - 10y = -2 • (5y - 32)
Final result :
-2 • (5y - 32)
3^2 + 4^2 = c^2
sqrt(9) + sqrt(16) = c^2
Sqrt(25) = c^2
C = 5
