Answer:
104.75°
Step-by-step explanation:
supplementary angles add up to 180°
therefore 180°-75.25°=104.75
In order to see how many real roots it has you have to see what the Δ is
So if Δ>0 then there are 2 real roots
If Δ=0 there is 1 real root
If Δ<0 no real root
And we know that:
Δ=b^2-4ac
So in the equation: Δ=b^2+4 and b^2 is always a number greater than or equal to 0 so when you add 4 to it, it is always greater than 0
So it has 2 real roots
Answer:
Step-by-step explanation: first you do 10 minus 2 you get 8
I believe it is A.
Option A is of two variables x & y and it is a straight line graph.
2x - 5 = y
7-12(3+b)=31
7-36+12b=31
-29+12b=31
12b=31+29
12b=60
b=5
