Answer:
A) (i) a = 95° (180 - 85), b = 85° (180 - 95), c = 85° (180 - 95), d = 95° (180 - 85)
A) (ii) a = 103° (180 - 77), b = 77° (180 - 103), c = 103° (180 - 77), d = 77° (180 - 103)
B) (i) 95 + 85 + 85 + 95 = 360°
B (ii) 103 + 77 + 103 + 77 = 360°
Tip: Angles on a straight line add to 180°
Hope this helps!
Answer: a
Step-by-step explanation:
We can find the distance between two points by using distance formula,

Here,
x₁ = -3
x₂ = 5
y₁ = -2
y₂ = 2
Therefore,

Hence the √80 = 8.94 approx is the distance between the two points (-3,-2) and (5,2).
Answer:
#1 is 31°
#2 is 120°
Step-by-step explanation:
You know that a triangle is 180°. In the first one its a right triangle, which means that angle is 90°. Subtract 90 and 59 by 180. The second subtract 36 and 24 by 180 to get your answer.
B. They are both congruent and similar
