Answer: Angles A and B are complementary angles

If Sin A ≈ 0.766 then Cos B ≈ 0.766.

If Cos B ≈ 0.766 then Sin A ≈ 0.766

Step-by-step explanation: In any given right angled triangle, one angle measures 90 degrees while the addition of the other two angles equals to 90 degrees. Hence if angle C is given as 90 degrees, then angles A and B added together equals 90 degrees (complementary angles equal 90 degrees).

Also, Sin A cannot be the same value as Sin B, since angle A and angle B are not equal in measurement. However, being complementary, the Sin of angle A equals the Cos of angle B.

If Sin A ≈ 0.766, then angle A ≈ 50 degrees

That makes angle B equal to 40 degrees. The Cos of B ≈ 0.766

Therefore if Sin A ≈ 0.766, then Cos B ≈ 0.766

If Cos B ≈ 0.766 then Sin A ≈ 0.766 are both correct

Justine answered 69 questions correctly on a 150 question test
MArishka [77]

Answer:

I am assuming you are asking for what percent correct she got. She got 46% correct.

Step-by-step explanation:

You divide the answers correct by the total questions. She got 69 out of 150, so dividing that is .46

To turn a decimal into a percentage, just move the decimal two places to the right, thus getting 46 %

If I assumed what you were asking incorrectly, let me know and I'll be happy to help!

A notebook that costs $0.75 to make in the factory is sold for $1.35.
kvasek [131]

Answer:

a) price markup $0.60

b) percent marked up 180%

Step-by-step explanation:

Amount marked up:

  1.35 - 0.75 = $0.60  

Percent markup:

  0.75x = 1.35

  x = 1.8 or 180%

Find the value of x need help
Kryger [21]

Answer:

Step-by-step explanation:

The supplement of 102 = 180 - 102 = 78

It is the interior angle of the given exterior angle.

It is also the enclosed angle of the isosceles triangle

Each of the other two angles = y

180 = 2*y + 78              Subtract 78 from both sides

180 - 78 = 2y                Combine

102 = 2y                       Divide by 2

102 / 2 = y    

51 = y

The smaller triangle on your right has  2 equal sides that are marked.

The angle you just found = <2 and the vertically opposite angle of the 51

So <2 = 51
