Answer:
x = 5, y = 4
Step-by-step explanation:
x + 4y = 21
4x - 16 = y
x + 4(4x - 16) = 21
x + (16x - 64) = 21
(17x - 64) = 21
17x = 85
x = 85/17
x = 5
___________________
x + 4y = 21
5 + 4y = 21
4y + 5 = 21
4y = 16
y = 16/4
y = 4

Answer:
2 Triangles can be made with the given measurements
Step-by-step explanation:
Start by solving for side b
b = 9/sin33 = appr 16.5
9<15<16.5 there are two possible triangles
sin33/15 = sinB/16.5 = sinB=(16.5sin33)/15
B=36.9, 180-36.9=143.1 Next determine if the angles are correct
36.9+33=69.9 143.1+33=176.1 Both of these are less than 180, two triangles can be drawn.
