Answer:
arc AC = 111°
Step-by-step explanation:
∠APC is a central angle, so arc AC is equal to the measure of ∠APC.
∠APC and ∠BPC are supplementary. So, m∠APC + m∠BPC = 180
m∠APC + 69 = 180
m∠APC = 111
arc AC = 111°
Inside the root is 50-1
50-1 = 49
You would remain with root 49 but, if you calculate the square root the answer would be 7 because...
7•7 = 49
^ So, the answer is 7
Answer:
False
Step-by-step explanation:
5x - 2y + 1 > 0
plug in the given ordered pair x= -2 and y = -1:-
5(-2) - 2(-1) + 1
= -10 + 2 + 1
= -7 which is less than 0 therefore the answer is False
