Answer:

A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).

Step-by-step explanation:

Find the value of X, rounded to the nearest tenth. <br> A. 31.8<br> B. 31.4<br> C. 10.3<br> D. 10.7
Alenkinab [10]

Answer:

B. 31.4

Step-by-step explanation:

To find x, the hypotenuse, we need to use sin because we have been given the <u>opposite</u> (the side opposite the angle 35°) and we need to work out the <u>hypotenuse</u> (the longest or <em>slanted</em> side):

SOH, CAH, TOA

sin(θ) = opposite ÷ hypotenuse

Sub in the values (we don't know the hypotenuse so i've called it x):

sin(35) = 18 ÷ x (multiply both sides by x)

x × sin(35) = 18 (divide both sides by sin(35))

x = 18 ÷ sin(35) = 31.38204...

x ≈ 31.4

Hope this helps!

mr jenson wants to tile a walkway that has an area of 3.6 square metres. He determines that he will need to use 250 square tiles
miskamm [114]

Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway.

What is the area of Square?

The area of a square is the product of the length of each side with itself, i.e. Area A = s x s where s is the length of each side of the square.

Mr. Jenson wants to tile 3.6 sq. meters or 36000 sq. cm.

Total number of tiles is 250.

Area of tile = \frac{Total covered area}{Number of tiles} = 36000/ 250    = 144 sq. cm

s X s = 144 sq. cm

s = \sqrt{144} cm

s = 12 cm

Thus, Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway..
