Using opposite outside angle on a circle is the inside angle times 2.

A is opposite the inside angle of 45, so a = 45 x 2 = 90 degrees.

Answer:

90%

Step-by-step explanation:

Complimentary means the same. And adding them together would equal 90. Just as you would divide 90 by 3, each individual angle would be equal to 30.

Is it possible for a figure to have 90° rotational symmetry but not 180° rotational symmetry.

Gre4nikov [31]

Answer:

Well, It is but not because..rotation symmetry, and a square has -turn (or 90-degree) rotation symmetry. As you may have already observed, many figures have 180-degree rotation symmetry but no other rotation symmetry. A figure has 180-degree rotation symmetry if it looks the same when turned halfway around...Soo yeah..I think I am right, So sorry if I'm wrong.

Answer:

50, 40, 30, 250, 350

Step-by-step explanation:

1/2 = 0.5, 0.5 x 100 = 50 (0.5 -> 5 -> 50)

2/5 = 0.4 (10 / 5 [the denominator] = 2, 0.2 x 2 [the numerator] = 0.4), 0.4 x 100 = 40 (0.4 -> 4 -> 40)

3/10 = (10 / 10 [the denominator] = 1, 0.1 x 3 [the numerator] = 0.3), 0.3 x 100 = 30 (0.3 -> 3 -> 30)

5/2 = 2.5 (2 1/2), 2.5 x 100 = 250 (2.5 -> 25 -> 250)

7/2 = 3.5 (3 1/2), 3.5 x 100 = 350 (3.5 -> 35 -> 350)

Note: I'm not sure if I understand the question completely, but I changed the fraction into a decimal and multiplied it by 100. Not sure what it means by "Divide fraction".

(H+k)-(j-2k) if h= -3 j= -2 and k= -9

nekit [7.7K]

If you change all the variables to the given valuables, the new equation would be (-3 + -9) - (-2 - 2 x -9)

Solve what's in the parenthesis first. -3 + -9 is -12. -2 x -9 is -18, and -2 - -18 is 16. Then you do -12 - 16 and you get -28

-28 is the answer :D
