Answer:
(-1,2) is domain
Step-by-step explanation:
Plug it in your y= screen of your graphing calculator and hit 2nd and then graph. it will give u a table of values
The midpoint of AC is (-1.5, 20)
Answer:
angle B: 39
AC: 7.288
AB: 11.58
(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)
Step-by-step explanation:
To solve this we will use SOH, CAH, TOA
we have the angle and the one opposite to it which means we can use either SOH or TOA
let's use TOA
tan(51)=(9/x)
x= 7.288
We can now use pahtagaryous theroem to solve for the hyptonouse
we have
9²+7.288²=C²
C=11.58
Finally, to find angle B we will recall that the angles of a triangle must add to 180.
51+90+a=180
a=39
That is quite simply and astoundingly:
3.482 x 10^9
