Answer:
<h2>
cos 30°= 0.866</h2>
Step-by-step explanation:
Step one:
Applying the SOH CAH TOA principle
assuming all dimensions are in cm
Step two:
Given data
opposite= 1 cm
hypotenuse= 2 cm
<h3>we can now solve for θ</h3>
Sin(θ)= opp/hyp
Sin(θ)= 1/2
Sin(θ)= 0.5
θ= sin-1 0.5
θ= 30°
hence from tables cos 30°= 0.866
(y+5)^2 + (x-1)^2 = 16
[^2 meaning squared]
Answer:
I pretty sure it's 86
Step-by-step explanation:
Let me know if it is right
Answer:
No Solutions
Step-by-step explanation:
Multiply the first equation by 5,and multiply the second equation by 2 to get a least common multiple for the x's.
5(4x+6y=3)
2(−10x−15y=−4)
It becomes:
20x+30y=15
−20x−30y=−8
Add these equations to eliminate y:
0=7
Answer:
No solutions.
