1. Obtuse Angle (see image 1). Obtuse angles are angles that are more than 90° in measurement but less than 180°
2. Right Angle (see image 2). Right angles are angles that have the measurement of 90°, and is formed by an intersection of two perpendicular straight lines.
3. Acute Angle (see image 3). Acute angles are angles that are less than 90° in measurement.

Answer:
a = 21
b = 63
c = 42√3
d = 21√3
Step-by-step explanation:
The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. The given side (42) is the longest side of the smallest triangle, and the shortest side of the largest triangle.
That means the other sides of the smallest triangle will be ...
a = 42/2 = 21
a+b = 2(42) = 84
b = (a+b) -a = 84 -21 = 63
d = 21√3 . . . . middle-length side of the smallest triangle
c = 42√3 . . . . middle-length side of the largest triangle
The values of the variables are ...
- a = 21
- b = 63
- c = 42√3
- d = 21√3
