The three inside angles of a triangle need to equal 180 degrees.

This means X = 180 - 43 - 59 = 78 degrees.

X and Z make a straight line that also needs to equal 180 degrees,

so Z = 180 - 78 = 102 degrees.

Y = 180 - 102 - 13 = 65 degrees.

A rectangular carpet measures 12m by 5m. Part of the carpet is covered by a square rug of length 2m. What fraction of the carpet

guajiro [1.7K]

Answer:

¹/15

Step-by-step explanation:

Area of the rug = s²

Where s = 2 m

Area of the rug = 2² = 4 m²

Area of the rectangular carpet = length × width

Where,

Length = 12 m

Width = 5 m

Area = 12 × 5 = 60 m²

Fraction of the carpet covered by the rug = area of the rug ÷ area of the carpet = 4/60 = ¹/15

Which equation represents the graph of y= cosx reflected across the x-axis then shifted vertically down by 2 units?

Phoenix [80]

Answer:

y = -cos(x) -2

Step-by-step explanation:

Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.

reflected: y = -cos(x)

then shifted: y = -cos(x) -2

What makes b in the equation true 3/8 X 8/b

Gala2k [10]

$\frac{3}{8} * \frac{8}{b} = \frac{3}{1} * \frac{1}{b}$ (I crossed simplify)

Next cross multiply;

3b = 1

b = 1/3

To check if the statement is true just substitute the value of b in the equation;

3b = 1

3(1/3) = 1

1 = 1
