Answer:
54
Step-by-step explanation:
Angles in a triangle add to 180° and we can see a right angle so
x = 180 - ( 90 + 36 )
x = 180 - 126
x = 54

Answer:
b = 4
r = 3
Step-by-step explanation:
r + b = 7
solve for 'r' to get r = 7-b
now substitute '7-b' for r in the second equation:
3.75(7-b) + 2.75b = 22.25
26.25 - 3.75b + 2.75b = 22.25
-b = -4
b = 4
r = 3
