The distance formula is d=\sqrt{(x_{2}, x_{1})^{2} +(y_{2}, y_{1})^2
7=x1
4=y2
-8=x2
4=y2
Just plug in the missing values into the equation and solve the equation :)
Answer:
C
Step-by-step explanation:
8i
√-64 = i√64 = 8i
Angle = 68⁰ is an inscribed angles, this angle equal 68⁰,
so it intersect arc = 2*68⁰= 136⁰.
Arc of the whole circle (circumference) =360⁰,and it also =b+104+136.
b+104+136 =360
b=360-(104+136) = 120⁰
Answer A. b=120⁰.
Answer:
5.7 in^2
Step-by-step explanation:
First find missing leg measurement a
a^2= c^2- b^2
a^2= 36-4
a^2= 32
a= 5.7
find area of triangle
a= AB/2
a= (2*5.7)/2
a= 5.7 in^2
