Answer:
yes i agree with you!!!
Step-by-step explanation:
To round 389,422 to the ten thousand, you need to go to the second number which is 8 and round it to the right. To the right of 8 is 9 so if a number is more than 5 you round 8 to 9. Then all the numbers after 8 turn into zeros
So... your answer is:
390,000

- 1/3 - 1 2/3 = - 2
When subtracting two negatives you add the two numbers together.
Answer:
x ≈ 77°, y = 103°
Step-by-step explanation:
Using the Sine rule in Δ BCD
= ( cross- multiply )
2.9sinx° = 4sin45° ( divide both sides by 2.9 )
sinx° = , thus
x = ( ) ≈ 77° ( to the nearest degree )
Since AC and DC are congruent then Δ ACD is isosceles.
Thus the base angles are congruent, that is
∠ ADC = ∠ CAD = y°
x and y are adjacent angles and supplementary, thus
x + y = 180, that is
77 + y = 180 ( subtract 77 from both sides )
y = 103°
