Answer:

15/2 sqrt(3) =z

15/4 sqrt(3) =y

Step-by-step explanation:

cos theta = adjacent side/ hypotenuse in a right triangle

cos 30 = z / 15

Multiply each side by 15

15 cos 30 = z

15 ( sqrt(3)/2)

15/2 sqrt(3) =z

sin theta = opposite side/ hypotenuse in a right triangle

sin 30 = y / z

Multiply each side by z

z sin 30 = y

z (1/2)=y

Z = 15/2 sqrt(3)

15/2 sqrt(3)*1/2

15/4 sqrt(3) =y

The scale factor of dilation from ABC to A^{1} B^{1} C^{1} is 0.333.

Step-by-step explanation:

Step 1:

First, we plot the coordinates of both triangles.

The coordinates of the triangle A^{1} B^{1} C^{1} are as follows;

A^{1} = (2, 3), B^{1} = (2, 1), and C^{1} = (3, 1).

The coordinates of triangle ABC are;

A = (4, 9), B = (4, 3), and C = (7, 3).

Step 2;

Next, we need to find the distances between at least two coordinates for both triangles.

The distances between vertical lines are found by calculating the difference in y values while for horizontal lines, the distances are found by calculating the difference between the x values.

The distance of A^{1} B^{1} = 3-1=2, the distance of B^{1} C^{1} = 3-2=1.

The distance of AB =9-3=6, the distance of BC = 7-4=3.

Step 3;

To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In this case, it is the length of the AB.

So The scale factor for AB = \frac{2}{6} = \frac{1}{3} = 0.333.

The scale factor for BC = \frac{1}{3} = 0.333.

Please help me if you can. Sorry if it’s blurry
jarptica [38.1K]

Step-by-step explanation:

oh, come on, just multiplication.

7.5×10⁴ years is 7.5×10000 =75000 years.

0.005 inches per year for 75000 years means

0.005 × 75000 = 5 × 75 = 375 inches.
