Answer:
x = 65
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for third angle
third angle = 180° - (60 + 55)° = 180° - 115° = 65°
65° and x are vertical angles and are congruent, thus
x = 65
Answer:
2x + 3 - 4/x
Step-by-step explanation:
6x^2 + 9x - 12/ 3x
1. Reduce the expression by cancelling the common factors.
2x^2 + 3x - 4/ x
2. Divide each term in the numerator by the denominator.
2x^2/x + 3x/x - 4/x
3. Simplify each term. Then when you finish to simplify your answwer would be: 2x + 3 - 4/x
i hope its helpful! :D
Since 2=3
And 3 and 7 are on a straight line so they add up to 180
You can say : x+ 2x= 180
3x=180
x=180/3
x= 60
Angle 2 is 60
