Write a two-columm proof

Mathematics
1 answer:
Nastasia [14]3 years ago

Both angles 2x+6 and 96 shown are vertically opposite angles and vertically opposite angles are always equal

so 2x+6 should be equal to 96

so 2x + 6 = 96

Now we have to solve for x here and have to get x by itself on left hand side

So first get rid of +6 by doing its opposite -6 on both sides

2x + 6 -6 = 96 -6

2x = 90

Now to get x by itself we have to get rid of 2, for that divide both sides by 2

\frac{2x}{2} = \frac{90}{2}

x = 45

Hence proved that x = 45

Divide 4897 by 6 step by step ​
Ratling [72]

Answer:

0816.166 recurring.

Step-by-step explanation:

6 times table : 6, 12, 18, 24, 30, 36, 42, 48.

6 \sqrt{4897}

6 ÷ 4= 0 so 6 didnt go into 4 leaving it to be a remainder so you carry the number over.

how many times does 6 go into 48, which is 8 times.

08 \\  6\sqrt{4897}

so far, this is what it would look like.

6 goes into 9, 1 leaving a remainder of 3,so we carry it over to the next number.

how many times does 6 goes into 37, which is 6 times leaving a remainder of 1.

0816 \\  6\sqrt{4897}

Now we need to go into the decimals because we still have a remainder.

6 \sqrt{4897.000}

so we now have 10, 6 goes into 10, 1 remainder 4.

how many times 6 goes into 40, 6, remainder 2.

6 goes into 20, 3 times remainder 4. this is going to end up recurring because we ended up with the same number so your full answer, putting all the numbers together would be

0816.166 recurring.

Can anyone help me!! You don’t have to answer all just one would be fine!
netineya [11]

Answer:

3. SinD= 12/15; Sin E= 9/15

4. sinD= 35/37; sinE= 12/37

5. sinD= 28/53; sinE= 45/53

6. Because the numerator should be 12 since that is the side opposite to the angle A.
