Answer:
59.0°
Step-by-step explanation:
Many triangle solvers are available for your phone, tablet, or browser. The attachments show the input and output of one of them.
___
You can use the law of cosines to compute the result yourself.
b^2 = a^2 + c^2 - 2ac·cos(B)
cos(B) = (a^2 +c^2 -b^2)/(2ac) = (22^2 +18^2 -20^2)/(2·22·18) = 408/792
B = arccos(408/792) ≈ 58.9924° ≈ 59.0°
(8x - 8y + 9) - (5x - 8y - z) = 3x + z + 9
8 - 5 = 3
-8 - (-8) = 0
9 - 0 =9
0 - (-z) = z
so it is written 3x +z +9
8/40 is equal to 20%-students
5/10 is equal to 50%- teachers
