Answer:
x = 9
∠B = 7 x 9 - 1 = 62°
∠BCD = 120°
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of two opposite interior angles
∠BCD = ∠CBA + ∠BAC
10x + 30 = (7x - 1) + (58)
10x + 30 = 7x + 57
3x = 27
x = 9
∠B = 7 x 9 - 1 = 62
∠BCD = 10 x 9 + 30 = 120
Answer:

Step-by-step explanation:
spanish = 30x + 579
French = 279 - 2x
3(217 - 2x) = 30x + 579
72 - 6x = 30x
+6x +6x
72 = 36x
2 years = x
