Answer:
8
Step-by-step explanation:
N an acute angle is 90 degrees or less and 90 + 90 is 180 and an obtuse angle is always more than 90 and always less than 180
Answer:
Step-by-step explanation:
- tangent = opposite / adjacent
- tan x = 40/34
- x = arctan (40/34)
- x ≈ 49.6°
Add like terms and put x in the middle.
-3 < -2x + x - 3x ≤ 5 - 2
-3 < - 4x ≤ 3
Sign changed when divide by negative numbers
(3/4) > x ≥ (-3/4)
