Answer: The largest angle is 7x

Step-by-step explanation:

Their sum is 180, so

3x + 5x + 7x = 180

5x = 180 --> x = 12

The largest angle is 7x, which is 7(12) = 84

Karolina [17]

Answer: 0.75

Step-by-step explanation:

We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.

We now have a triangle with the values of:

x = 4

y =3

h^2= 4^2 + 3^2

h^2 = 16 + 9

h^2 = 25

h = 5

Tangent = opposite/adjacent

= y/x

= 3/4

= 0.75

Answer:

x= 13

Step-by-step explanation:

−4/9(18x − 36) = −88

we need to solve the equation for x

$\frac{-4}{9}(18x - 36) = -88$

First we remove the fraction -4/9

Multiply by -9/4 on both sides

$\frac{-9}{4}*\frac{-4}{9}(18x - 36) = -88*\frac{-9}{4}$

18x -36 = 198

Now add 36 on both sides

18x = 234

Divide both sides by 18

x = 13

fenix001 [56]

Answer:

Yellow Bin

Step-by-step explanation:

<u>Yellow Bin</u>

Length = 11.4 inches,

Width = 4.2 inches,

Height = $\frac{8}{3}$

Volume of the yellow bin=LWH $=11.4 X 4.2 X \frac{8}{3}=127.68 \:cubic \:inches$

Length = 9 inches,

Width = 5.45 inches,

Height = $\frac{11}{5}$

Volume of the red bin=LWH $=9X 5.45 X \frac{11}{5}=107.91 \:cubic \:inches$

The yellow bin has a greater volume since 127.68 is greater than 107.91.
