X is 90°
A triangles angles add up to 180° so
180 - 47 - 90 = y
180 - 137 = y
y = 43°
Answer:
I think the answer would be
Alloy A 30%
Alloy B 40%
The reason I say that is because Alloy B has a higher amount of pure silver so yeah
I hope this helps mark me brainliest and tell me if I'm wrong please so Then I could fix it.
P.S. Wegnerkolmp2741o is gonna answer so I would go with his
<span>Clarke
borrows $16000 to buy a car he pays simple interest at an annual rate of 6%
over a period of 3.5 years how much does he pay all together?
Let’s calculate
=> 16 000 dollars is the amount he borrowed
=> 6% is the annual interest
=> 3.5 years us the total years that he will be paying it.
Solutions:
=> 16 000 dollars * .06 = 960 dollars is the annual interests
=> 960 * 3.5 = 3 360 dollars for 3.5 years
=> 16 000 + 3 360 = 19 360 dollars

Answer:
θ = 2π/3 or 5π/3
Step-by-step explanation:
2 cosθ + 1= 0
when + 1 goes to R H S Side than it becomes negative by transposition method
2 cos = -1
now by dividing by 2 both sides we get
cosθ = -
since cosθ is negative
Cosθ = - cos 60°
it means either cosθ lies in 2nd or third quadrant
θ = π - π/3
or
θ = 2π- π/3
so θ = 2π/3 or 5π/3
