Tbh I don’t know and I hope someone gives you the answer
Given a point in coordinates form

, one can compute the cartesian form like this:

We have:

We get the cartesian form then:
B. 68
I use the formula A= bh/2 it’s the same thing
8x17 = 136
136/2 = 68
Answer:
65
Step-by-step explanation:
Answer:
120°
Step-by-step explanation:
To find angle BCD, we need to spot that the angle is on a straight line (ACD); angles on a straight line add up to 180°. This means we can find the missing angle by doing 180 - 60 which is 120°.
Hope this helps!
