Answer:
2(k + 9) = 4
Step-by-step explanation:
Use distributive property.
2 x k = 2k
2 x 9 = 18
Equation:
2k + 18 = 4
Subtract 18 from both sides
2k = -14
Divide both sides by 2
k = -7
Answer:
cos(55) = 11/x
Step-by-step explanation:
We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.
5, 10, 30, 60, 180, 360, 1,080
5*2=10
10*3=30
30*2=60
60*3=180
180*2=360
360*3=1,080
