Answer:

∠ A ≈ 35.54°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = $\frac{opposite}{adjacent}$ = $\frac{BC}{AC}$ = $\frac{5}{7}$ , thus

A = $tan^{-1}$ ( $\frac{5}{7}$ ) ≈ 35.54° ( to the nearest hundredth )

Find the size of angle YZX

Tasya [4]

Answer:

21.001 cm

Step-by-step explanation:

The diagram shows right triangle with

Hypotenuse ZY = 22.3 cm

Leg XY = 7.5 cm

By the Pythagorean theorem,

$XY^2+XZ^2=ZY^2\\ \\7.5^2+XZ^2=22.3^2\\ \\XZ^2=22.3^2-7.5^2\\ \\XZ^2=(22.3-7.5)(22.3+7.5)\\ \\XZ^2=14.8\cdot 29.8\\ \\XZ^2=441.04\\ \\XZ=\sqrt{441.04}\approx 21.001\ cm$

Fancy goldfish x cost $3 each and common goldfish y cost $1 each.

babunello [35]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x------> the number of fancy goldfish

y-----> the number of common goldfish

we know that

The linear equation that represent the situation is equal to

$3x+y=20$

Isolate the variable y

$y=-3x+20$

To graph the line find the intercepts

The x-intercept is equal to the point $(6.667,0)$ ----> value of x when the value of y is equal to zero

The y-intercept is equal to the point $(0,20)$ ----> value of y when the value of x is equal to zero

Plot the points

The graph in the attached figure

The solution of the problem is all positive ordered pairs of whole numbers belong to the line

The possible solutions are

For $x=0$ ------> $y=-3(0)+20=20$

For $x=1$ ------> $y=-3(1)+20=17$

For $x=2$ ------> $y=-3(2)+20=14$

For $x=3$ ------> $y=-3(3)+20=11$

For $x=4$ ------> $y=-3(4)+20=8$

For $x=5$ ------> $y=-3(5)+20=5$

For $x=6$ ------> $y=-3(6)+20=2$

The domain (number of fancy goldfish) is the interval---------> $[0,1,2,3,4,5,6]$

The range (number of common goldfish) is the interval---------> $[20,17,14,11,8,5,2]$
