Answer:
The missing side has a length equal to 
Step-by-step explanation:
We need to find the length of the missing side on the right triangle. We were given the length of the hypotenuse, and the opposite cathetus, therefore we can use the sine relation. This is done below:

The answer is multiplication
Perimeter = length * 2 + width * 2. x = width. 2x = length. perimeter = 2(x) + 2(2x). perimeter = 2x + 4x. 60 (perimeter) = 6x. divide both sides by six. x = 10. width = 10. length is 2(width), so length is 20.
Answer:
The coaster’s radius is 5 cm
Step-by-step explanation:
Drink Coaster has a circular shape.
Area of a circle = π*r²
so, area of the drink coaster = π x (Radius of the drink coaster)²
Given that Area of the drink coaster is 78.5 cm²
∴ 78.5 cm² = π*r²
Also we are to use 3.14 for π
∴ 78.5 cm² = 3.14*r²
r² = 78.5 cm² / 3.14
r² = 25 cm²
r =
cm
r = 5 cm
Hence, the coaster’s radius is 5 cm
Answer:
False
Step-by-step explanation:
Equilateral triangles can only be acute.
Because a triangle can only have 180 degrees in angles, in an equilateral triangle all angles must be less than 90 degrees since they all measure the same (60 degrees)
