Answer:
a concave lens is exactly the opppostie with outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.
Step-by-step explanation:

Step-by-step explanation:
largest angle: 3x
smallest angle: x
third angle: 3x - 23
The sum of the angles of a triangle equals 180°
(3x) + (x) + (3x -23) = 180
7x - 23 = 180
7x = 203
x = 29
largest angle: 3x = 3(29) = 87
third angle: 3x - 23 = 3(29) - 23 = 87 - 23 = 64
Answer: 29°, 64°, 87°
