Answer: Supplementary angles have a sum of 180 degrees so you would subtract 79 from 180 to determine the value of its supplement which would be 101 degrees

While complementary angles have a sum of 80 degrees. So you would subtract 59 from 80 and that leaves you with 21, so the complement angle is equal to 21 degrees

Bridget takes a 5-inch by 4-inch rectangle of fabric and cuts from one corner of the piece of fabric to the diagonally opposite
mario62 [17]

Answer:

Perimeter of each triangles are equivalent to 15.4 inches.

Step-by-step explanation:

Given:

A rectangle :

Length of the rectangle = 5 inches

Width of the rectangle =4 inches

As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.

The diagonal will be treated as the hypotenuse.

Lets say that the length of the hypotenuse is 'x'.

Using Pythagoras formula:

⇒ (hypotenuse) = \sqrt{(perpendicular)^2+(base)^2}

Plugging the values:

⇒ hypotenuse = \sqrt{5^2+4^2}

⇒ hypotenuse = \sqrt{25+16}

⇒ hypotenuse =\sqrt{41}

⇒ hypotenuse = 6.40  inches

Now we have to find the perimeter :

Perimeter = Summation of length of all sides.

So,

Perimeter  of each triangle = (length + width + hypotenuse)

⇒ Perimeter =(5+4+6.4)

⇒ Perimeter =15.4  inches

Perimeter of each triangle, as they are equally sized are same that is   15.4 inches.

Answer:

1/8 + 1/2 = 5/8

Step-by-step explanation:

Total number of beads = 8

Number of green beads = 4

Number of yellow beads = 1

Fraction of green beads :

Number of green / total number of bead = 4 / 8 = 1/2

Fraction of yellow beads :

Number of yellow / total number of bead = 1 / 8

Number of green or yellow bead :

1/8 + 1/2 = (1 + 4) / 8 = 5/8

Can anyone help and show work
Romashka [77]

Answer:

x=88⁰

Step-by-step explanation:

Since the value of that angle is 44⁰ and the angle is located on the circle, the measure of the arch x is twice the angle value.

So x=2×44⁰=88⁰
