satela [25.4K]3 years ago

Answer:

cos 0=90 degrees

Step-by-step explanation:

If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.

\sin(90)  =  \cos(0)

and since sin 90 equal 1 cos of 0 equal 1.

What if we switch angles

Well they are still equal

\sin(0)  =  \cos(90)

But this time sin of 0 is 0 and cos 90 is 0.

A rectangular painting by Leonardo da Vinci measured 62cm along its diagonal. If the painting has a height of 42 cm how wide is
IRINA_888 [86]

ANSWER

45.6cm to the nearest tenth.

EXPLANATION

The diagonal of the rectangular painting is 62cm.

The height of the painting is 42 cm.

The height of the painting h , the diagonal, and the width of the painting forms a right triangle with the diagonal being the hypotenuse.

From the Pythagoras Theorem,

{w}^{2}  +  {42}^{2}  = {62}^{2}

{w}^{2} = {62}^{2} -  {42}^{2}

{w}^{2}  = 2080

{w} =  \sqrt{2080}

w = 4 \sqrt{130}

The width of the painting is 45.6cm to the nearest tenth.

Morgan’s grandmother orders her groceries online and has them delivered to her house. Her bill is $120. She has a coupon for 20%
iragen [17]

Answer:

The total price of the groceries, including discount and tip is $110.4.

Step-by-step explanation:

Here, the bill amount of groceries   = $120

Now, the coupon off  = 20%

Calculating the discount, we get

20% of bill amount $120  =   20% of 120  = \frac{20}{100}  \times 120  = 24

So, the 20% discount on the bill amount = $24

The actual payable amount = Bill Amount  - Discount

                                                =  $120 - $24  = $96

Now, 15% tip is also applied on the actual payable amount $96.

15% of 96 = \frac{15}{100}  \times 96  = 14.4

So, the total price t  = Payable amount + Tip amount

                                 = $96 +  $14.4   =  $110.4

or, t = $110.4

Hence, the total price of the groceries, including the discount and the tip  is  t = $110.4.
