Answer:
X = 276°
Step-by-step explanation:
Divide X into x1 and x2
then then using the trick of co-interior angles, find the answer of x1 and x2 . then add x1 and x2
Answer:
-2 , 4
Step-by-step explanation:
(x - 1)² – 9=0
(add nine to both sides)
(x - 1)² = 9
(square root both sides)
x - 1 = (positive or negative) 3
(add 1)
x = 4 or -2
Answer:
The answer would be -75
Step-by-step explanation:
|x – 55| = 4.2
where x is the speed.
-4.2 < x - 55 < 4.2
-4.5 + 55 < x < 55 -4.2
50.8 < x < 59.2
The upper boundary for x is 59.2
The speed must be in the range 55 - 4.2 to 55 + 4.2.
Prop Q because the line opposite is the biggest making it the widest angle
