1) Geometric sequence

2) Arithmetic sequence

3) Arithmetic sequence

4) Geometric sequence (actually I’m not really sure because I looked this one up and it says it is neither arithmetic or geometric because there is no common difference)

Anyways, I hope this helps! You may want to check if that last answer is correct but hope you have a wonderful day ;)

Answer:

$BC = 8 \sqrt{2}$

Step-by-step explanation:

$\sin(45) = \frac{opposite}{hypotenuse}$

$\sin(45) = \frac{8}{BC}$

$(BC) \sin(45) = \frac{8}{x} (BC)$

$(BC) \sin(45) = 8$

$\frac{(BC) \sin(45) }{ \sin(45) } = \frac{8}{ \sin(45) }$

$BC = \frac{8}{ \sin(45) }$

$BC = 8 \sqrt{2}$

The sixth-grade art students are making a mosaic using tiles in the shape of right triangles.each tile has leg measures of 3 cen

vichka [17]

Area of a right triangle is equal to (the length times the height) divided by 2

So the area of each tile is (3 x 3) / 2 = 4.5 square centimeters

200 tiles equal 200 x 4.5 = 900 sq cm
