Use the diagram to find the measure of each angle. Enter the number only.
Pavlova-9 [17]

9514 1404 393

Answer:

  a = 64, b = 90, c = 26, d = 90, e = 26, f = 120, g = 120, h = 60,

  i = 56, j = 124, k = 56

Step-by-step explanation:

Vertical angles are congruent; linear pairs are supplementary; two angles dividing a right angle are complementary. These are the angle relations you need to know to solve this.

__

Working from the top and from the given angles, ...

  h = 60°

  f = g = 180° -h = 120°

  j = 124°

  k = i = 180° -124° = 56°

  a = 64°

  b = d = 90°

  c = e = 90° -64° = 26°

In summary, measures in degrees are ...

  a = 64, b = 90, c = 26, d = 90, e = 26, f = 120, g = 120, h = 60,

  i = 56, j = 124, k = 56

Someone please help me!!! I’m stuck and need help!
denpristay [2]

Answer:

12

Step-by-step explanation:

These triangles are similar using the AA theroem. This means there sides are in corresponding proportion.

Side AR and Side TE are corresponding. Use this proportion.

\frac{6}{8}

This side the triangle SAR side lengths are 3/4 of side lengths of triangle SET.

We know that RS+ST=21

And that RS=3/4(ST).

\frac{3}{4} x + x = 21

1.75x = 21

x=12.

Side ST is 12

A 5-pound bag at Bargain Mart costs $6.45. A 2-pound bag at Food Saver costs $2.50. A 7-pound bag at Grocery Surplus costs $9.45
levacccp [35]

Answer: Food Saver

Step-by-step explanation:

A 5-pound bag at Bargain Mart costs $6.45. The coat per pound will be:

= $6.45 / 5

= $1.29

A 2-pound bag at Food Saver costs $2.50. The cost per pound will be:

= $2.50 / 2

= $1.25

A 7-pound bag at Grocery Surplus costs $9.45. The cost per pound will be:

= $9.45 / 7

= $1.35

A 10-pound bag at Economart costs $12.89. ​The cost ​per pound will be:

= $12.89 / 10

= $1.289

Therefore, the shop which sells flour for the lowest unit price is Food Saver.
