Step-by-step explanation:
Since the triangles are right use trigonometric ratios to find x and y
A
sin33° = 
= 
Multiply both sides by x
x × sin33° = 2.5 ( divide both sides by sin33° )
x = 
≈ 4.590
tan33° = 
= 
Multiply both sides by y
y × tan33° = 2.5 ( divide both sides by tan33° )
y = 
≈ 3.850
B
cos72° = = 
Multiply both sides by x
x × cos72° = 6 ( divide both sides by cos72° )
x = 
≈ 19.416
tan72° = 
Multiply both sides by 6
6 × tan72° = y, thus
y ≈ 18.466
Step-by-step explanation:
on line AB
X + 117 = 180 ( Angle sum property )
X = 63°
and
X+Y = 90° (given )
63° + Y = 90°
Y = 27°
Answer:
A classroom is arranged with 8 seats in the front row, 10 seats in the middle row, and 12 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom.
