X + y = 90
Let's make 'x' the bigger angle and 'y' the smaller.
X is 24 more than twice y.
x = 24 + 2y
Now plug that into the x of the first equation.
(24 + 2y) + y = 90
Combine like terms.
24 + 3y = 90
Subtract 24 from both sides.
3y = 66
Divide both sides by 3.
y = 22
The measure of the smaller angle is 22°
Let's say b equals 2
2^4=16
16*2= 32
This is what I could make of the question
Check the picture below.

since the width is just a dimension unit, it can't be -31.
what is the length? well, the length is w + 30.
23
Step-by-step explanation:
angle DEF = 74 degrees.
well I would use sins but it's quite simple
Length of DE is 23, just like AB
