Answer:
B
Step-by-step explanation:
Since the triangle is right use the sine/ tangent ratios to solve for x and y
note sin60° = and tan60° =
sin60° = =
ysin60° = 3
y × = 3
multiply both sides by 2 and divide by
y v= 6 = 6
tan60° = =
xtan60° = 3
x × = 3
divide both sides by
x = 3 = 3

Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴ =
∴ x = 3
∴ The value of x is 3
