Answer:
87 is the number
Step-by-step explanation:
 
        
             
        
        
        
X + y = 180
x = 4y 
Plug that in and you get: 4y + y = 180
5y = 180
y = 36
If you want the larger angle, simply plug in y to x = 4y
So: x = 4(36) = 144
The smaller angle is 36 degrees, and the larger angle is 144 degrees.

Answer:
D. d = 5
Step-by-step explanation:
d = d² - d¹
 = 5 - 0
 = 5
d = d³ - d⁴
 = 10 - 5
 = 5
d = dⁿ - dⁿ-¹
