The laws of sines is already indicated in the provided images.
1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,
sin20/3.3 = sin(126)/b
b = 7.8 units
From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.
2. Angle J = 180 - 120 - 40 = 20 degrees. Then,
sin(20)/2 = sin(120)/k
k = 5.1 units</span>
According to multiplication you can use repeated addition to get the same product of the given equation.
Ex: 5x2= 2+2+2+2+2 ( 5 groups of 2)
Both will give you same answer (10).
Hence 2 x 3/4 = 3/4 + 3/4
Answer:
D. 5y^2
Step-by-step explanation:
2x + 3y^2 - 2(x - y^2)
2 * x = 2x
2 * -y^2 = -2y^2
2x + 3y^2 - 2x + 2y^2
Combine like terms
2x and -2x cancel ach other out
3y^2 + 2y^2 = 5y^2
D. 5y^2
<span>To find the standard form for 200,000+80,000+700+6, simply add these numbers together:
</span>200,000+80,000+700+6= <span>280,706
