Answer:

a° = 52°

b° = 64°

c° = 128°

Step-by-step explanation:

a) The 52° angle and the angle marked a° both intercept the same arc, so have the same measure.

a° = 52°

__

b) The base angles of the isosceles triangle are equal. This means they are ...

b° = (180° -52°)/2 = 128°/2

b° = 64°

__

c) The arc intercepted by angle b° is twice the measure of angle b°, so is ...

c° = 2(64°)

c° = 128°

There are 84 classes in a school. Two-thirds learned about the Holocaust. The rest did not. How many classes did not learn about the Holocaust?

Answers

Answer:

28 classes

Step-by-step explanation:

84/3 = 28 classes

Answer:

28 classes didn't learn about the Holocaust

Step-by-step explanation:

If there are 84 classes and two-thirds learned about the Holocaust that means that you have to divide by three.

84 ÷ 3 = 28

Then, you can check your answer by multiplying 28 × 3 = 84

Two numbers are in the ratio 7 : 4 . If their difference is 18, then find the numbers.

Answers

Answer:

x = 24

. So, first number = 7 * 24 = 168. and second number = 4 * 24 = 96. Therefore the numbers are 168 and 96.

Answer:

42 and 24

Step-by-step explanation:

The numbers in ratio 7 : 4 = 7x : 4x ( x is a multiplier ) , then

7x - 4x = 18 ( difference of 2 numbers is 18 )

3x = 18 ( divide both sides by 3 )

x = 6

Then

7x = 7 × 6 = 42

4x = 4 × 6 = 24

The numbers are 42 and 24

it's -63

good luck if you want explanation comment

Answer: 63

Step-by-step explanation:

All triangles' angles added up should be 180 degrees, so 70+47=117 and 180-117=63.

180 = a+b+c

180 = 47 + 70 + c

180 - 47 - 70 = c

or,

180 - (47+70) = c
