Answer: The answer is (A) complementary angles.

Step-by-step explanation: We are given a figure involving angles 1 and 2 and we are to select the correct relation between these two angles.

We have

$\angle 1+\angle 2+90^\circ=180^\circ,~\textup{measure of a straight angle is 180 degrees}\\\\\Rightarrow \angle 1+\angle 2=180^\circ-90^\circ\\\\\Rightarrow \angle 1+\angle 2=90^\circ.$

We know that, if the sum of two angles is 90°, then they are said to be complementary angles.

Thus, ∠1 and ∠2 are complementary angles.

Thus., (A) is the correct option.

Tanya opened a savings account with a deposit of 550.she deposited 450 in the first week and withdrew $120in the second week of

Afina-wow [57]

Just do this 550+450=1000-120=880=750=1630 Now I assume that what you meant to say was what percent of the new balance was the last deposit made. So thats what Im going to be answering off of. We would need to take 1630-750=880 then 880/1630=.54 (rounded to the nearest hundredth) then we need to subtract 54 from one hundread because .54 is how much that the account overgoes the latest deposit making are final answer. That the last deposit that she mad accounted for 46% of the entire account. Enjoy!=)
