Answer:
In a triangle, sum of three angles=180°
So, A+B+C=180
C=180-A-B
C=180-60-a-60+a
C=60°
Hope it helps :-)
Answer:
Step-by-step explanation:
1) In the first equation, - 4x was added to both sides of the equation. This is expressed as
6x - 4x + 9 = 4x - 4x - 3
2x + 9 = - 3
2) In the second equation, both sides of the equation was multiplied by - 1/4. This is expressed as
- 4 × - 1/4(5x - 7) = - 18 × - 1/4
5x - 7 = 4.5
3) In the third equation, - 4 was added to both sides of the equation. This is expressed as
8 - 10x = 7 + 5x
8 + (- 4) - 10x = 7 + (-4) + 5x
8 - 4 - 10x = 7 - 4 + 5x
4 - 10x = 5 + 5x
4) In the fourth equation, both sides of the equation was multiplied by - 4. This is expressed as
- 5x/4 × - 4 = 4 × - 4
5x = - 16
5) In the fourth equation, both sides of the equation was multiplied by 1/4x and 1/4. This is expressed as
12x × 1/4x + 4 × 1/4 = 20x × 1/4x + 24 × 1/4
3x + 1 = 5x + 6
// I AM NOT SURE, IF SOMEONE SEES THIS AND ITS WRONG CORRECT ME DIRECTLY.
hmm.. never heard of properties but take a look at this :D
