Answer:
Step-by-step explanation:
According to the diagram ,
Hypotenuse = 10√3
Opposite = x
Adjacent = y
α = 60
Using SOHCAHTOA ,
Sin α = opp / hyp
Sin 60= x/10√3
√3/2= x/10√3
x = 15
Pythagoras theorem ;
Hypotenuse ^2 = Opposite ^2 +Adjacent ^2
10√3 ^2 = 15^2+ y^2
300 = 225 +y ^2
300 -225 = y^2
75 = y^2
y = √75y
y = 5√3
Answer:
<u>4.33</u>
Step-by-step explanation:
- 2N + 7 = 5N - 6
- 3N = 13
- N = 13/3
- N = <u>4.33</u>
The first answer is -15-20x.
The second answer is -42b-21.
Ask in the comments section if you want me to explain, other than combining like terms and using the distributive property. I hope this helps!

Answer:
0.01167
Step-by-step explanation:
180 - 0.669 = 89.331
complementary angle = 89.331
cos(89.331) = 0.01167
