Answer:

<U+<V +< W = 180°[sum of interior angle of a triangle is 180°]

3x+9° +30° + 24° = 180°

3x + 45° = 180°

3x = 180° -45° = 135°

x = 135/3

x = 45°

THEOREM:

Angle sum property —: The sum of interior angles of a triangle is 180°.

ANSWER:

<u>By angle sum property</u>,

∠U + ∠V + ∠W = 180°

3x - 9° + 30° + 24° = 180°
3x + 45° = 180°
3x = 180° – 45°
3x = 135°
x = 135/3
x = 45°

So, <u>Correct choice</u> - [C] 45°.

mojhsa [17]

Answer: 1,250

Step-by-step explanation:

Given: The total number of students in the school= 25,000

Since each class has 10 students , therefore, the number of classes in the school= $\frac{25000}{10}=2500$

Also, Each student takes 2 classes a day, thus the number of classes taken by total teachers in a day = $2\times2500=5000$

Also, each teacher teaches 4 classes.

Then the number of teachers in the school = $\frac{5000}{4}=1250$

Hence, the number of teachers are at Big Big School = 1,250

Mr. Jefferson has 20 students in his class. He wants to send 4 of these students to pick up books for the class. How many combin

Minchanka [31]

Answer:

4845 combinations

Step-by-step explanation:

Whenever there is a selection of some elements from a certain group, there are several ways to do so. There are different combinations from the group which can be selected. The concept of combination means that there are certain number of elements to be selected from the group and there is no importance given to the order of the selection. The total number of students are 20, and 4 out of them have to be selected. It can be clearly seen that the order of selection does not matter, therefore the formula to be used is:

Combinations = 20C4 = (20*19*18*17)/(4*3*2*1) = 4845.

So the correct answer is 4845 combinations!!!
