Answer:
35/ 18
(Decimal: 1.944444)
Step-by-step explanation:
If your writing the equation it would be e subtracted by 5 equals 18 so it would look like e-5=18
I believe the answer is 45 because squares cut in have 2/3 of the ends are 45 degree angles.
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
