Step-by-step explanation:
AB=√(-2-3)²+(6+1)²=√(25+49)=√(74)
Answer:
Look Below
Step-by-step explanation:
It reveals what type of slope it has. It reveals whether it is positive or negative. It tells when the line will cross the Y-Axis. This is just the groundwork of it but there is a whole list I think on what one equation can reveal about a line on a graph. Hope This Helps! If you find any fault in my answer please let me know! Have a good day!
Given : 
Multiplying and Dividing with (2 + 5i)
We know that i² = -1
Option C is the Answer
Answer: B
Step-by-step explanation:
The problem statement tells us that
- AM ≅ MB, ∴ ΔAMB is isosceles
- AM ≅ MC, ∴ ΔAMC is isosceles
Base angles of an isosceles triangle are equal, so ∠MAB ≅ ∠MBA. ∠AMC is the exterior angle opposite those two, so it is equal to their sum, 2∠MAB.
The base angles in isosceles ΔAMC are equal to half the difference between the apex angle, ∠AMC, and 180°. That is,
... ∠MAC = (1/2)(180° -∠AMC) = (1/2)(180° -2∠MAB) = 90° -∠MAB
The angle at A of ΔABC is the sum of the two angles created by the median AM. That is ...
∠A = ∠MAC + ∠MAB
∠A = (90° -∠MAB) +∠MAB
∠A = 90°
_____
Maybe a shorter way to get there is to realize that ...
... MA ≅ MB ≅ MC
so M is the center of a circle with BC as a diameter and A a point on the circle. Angle BAC is inscribed in the semicircle and subtends an arc of 180°, so angle A is 90°.
