squares of w and x is equal to w² and x² so, their sum means they are going to add.
3 + (w² + x²) = 32

Can someone help me with 1& 2 will mark brainiest
melamori03 [73]
Sin 45° = opposite side / hypotenuse

1/2 = 8/h
h = 16

2)6/12 = 1/2
1/2 = sin 45°

6√3/12 = √3/2
√3/2 = cos 30°

Sum of angles of triangle = 180°
The 3rd angle = 180 - (45 + 30) = 180 - 75 = 105°

Angles = 30° , 45° , 105°

Ahat [919]

Answer:

20 grams

Step-by-step explanation:

Let x be the total allowance of fat

16 grams is 80% of his total allowance

x * 80% = 16

Change percent to a decimal

x *.8 = 16

Divide each side by .9

.8x/.8 = 16/.8

x = 20

Solve for x <br> (19x-18) <br> (7x+1) <br> (10x-9)
ExtremeBDS [4]

Answer:

Step-by-step explanation:

Exterior angle property: Exterior angles equals the sum of remote angles

19x - 18 = 7x + 1 + 10x - 9

19x - 18 = <u>7x + 10x</u> + <u>1 - 9 </u>    {Combine like terms}

19x - 18 = 17x - 8          {Subtract 17x from both sides}

19x - 17x - 18 = -8

        2x - 18 = -8         {Add 18 to both sides}

              2x = -8 + 18

             2x = 10

              x = 10/2

x = 5

What is the percent of the discount?
Setler79 [48]

The full price is $82, (100%), the discounted price is $65.60, (?%)

So lets see something:

$82 ------------- 100%

$65.60 --------------- x%

Multiply in cross

82.x = 65,60 . 100

82x = 6560

Divide both sides by 82

82x/82 = 6560/82

x = 80

So the discounted price is equal to 80% of the initial price

100% - 80% = 20% so the discount is 20%
