Answer:
<h2> 23-[12+{16-(12÷3)}] = - 1 </h2>
Step-by-step explanation:
23 - [12 + {16 - (12÷3)}] =
= 23 - [12 + {16 - 4}] =
= 23 - [12 + 12] =
= 23 - 24 =
= - 1
Answer:
1- a
2- b
3- c
4- d
Step-by-step explanation:
For any operation you have to separate the numbers from the unknown quantities (x, y) and then simplify them by solving them with quantities you are familiar with.
Example:
7x + 8 - 6 + 3x
7x + 3x + 8 - 6
you can only solve operations if they are both natural or algebraic numbers
10x + 2

Answer:
x + 20° = 35.56°
3x + 10° = 56.68°
5x + 10° = 87.8°
Step-by-step explanation:
Assume;
Given measures are angle of a triangle
x + 20°
3x + 10°
5x + 10°
Find:
Value of each angle
Computation:
We know that, sum of all interior angle in a triangle is 180°
So,
We say that
x + 20° + 3x + 10° + 5x + 10° = 180°
9x + 40° = 180°
9x = 140°
x = 15.56°
So,
x + 20° = 15.56 + 20 = 35.56°
3x + 10° = 3(15.56) + 10 = 56.68°
5x + 10° = 5(15.56) + 10 = 87.8°
