Answer:
27°
Step-by-step explanation:
- A tangent meets a radius at 90°
- Angles in a trainable sum to 180°
- 180 - 90 - 63 = 27°
1.994 x 10^-23
-0.167 x 10^-23
1.827 x 10^-23
Correct answer is the second one.
Answer:
Step-by-step explanation:
-3(x-2)=12
-3x+6=12
subtract 6 from both sides
-3x+6-6=12-6
-3x=6
divide by -3
-3x/3=6/-3
x=-2
Answer is 105 degrees.
Explanation:
Given two parallel lines AB and CD and a transversal cutting the two lines.
We know that when a transversal cuts two parallel line,
i) corresponding angles would be equal
ii) Interior angles total to 180
iii) alternate angles are equal.
In the picture given we have corresponding angles as
(2,6) . Hence angle 2 = angle 6.
Angle 6 = 75 (given)
Hence angle 2 =75.
Angles 1 and 2 are supplementary because they form a linear pair.
Hence angle 1 = 180-75
Angle 1 =105
