Answer:
you answer is going to be 17
Step-by-step explanation:
Multiply it out. 3*1+3*4t=3+12t
Its 12, becuse if its a Circle then you can look at it the same way you look at a clock which has 12 numbers on it and 4 and 11 are directly across each other.
a^2 + b^2 = c^2 is right a^2 + b^2 > c^2 is acute a^2 + b^2 < c^2 is obtuse
a^2 + b^2 = c^2
18^2 + 23^2 = 30^2
324 + 529 = 900
853 < 900
obtuse
