Describe the pair of angles shown in the figure.

D

Step-by-step explanation:

As, complementary angles are those which add up to 90°,but those add up to 100°.So not option A

And it not supplementry angles because tge angles that add a 180°,so not option B

And not vertical, because if it was vertical then both of the angles would be equal so not option C

It is D because they both are adjacent to each other, therefore it is option D

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
