. The sum of angels in the triangle must be 180
Therefore
1) 180 - (40+85)= 55
2)180-(14+30)= 136
Answer: 42
Step-by-step explanation:
Complementary means they add up to 90 degrees
so 90-48=42
360 ÷ 6 = 60 (Angles at a point)
Answer: 60°
Answer:
[2, 6].
Step-by-step explanation:
Notice that there is a red line (graph) only for [2, 6]. Thus, the domain of this function is [2, 6].
Answer:
C) The discriminant is 0.
Step-by-step explanation:
Since the graph of the quadratic equation has only one x-intercept, we can conclude that the quadratic has only one real root.
If a quadratic equation has only one real root, then the discriminant is 0
