By definition of absolute value we have two equalities:
2x + 1 = 10
2x + 1 = -10
For 2x + 1 = 10:
2x + 1 = 10
2x = 10-1
2x = 9
x = 9/2
For 2x + 1 = -10:
2x + 1 = -10
2x = -10-1
2x = -11
x = -11 / 2
Answer:
{-11/2, 9/2}
Answer:
20cm Perimeter: 90
Step-by-step explanation:
Hope this helps!(^-^)
Let the angle be x and its complement be y and its supplement be z
Then A/Q
x +y = 90°
x = 90° - y -----(¡)
And x+z = 180°
From ques. z = 5y
Then x + z = 180°
x + 5y = 180°
From (¡) 90 - y +5y = 180
90-4y = 180
y = 90/4 = 22.5°
x = 90- 22.5
= 67.5
