Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18
So the first angle is 18° and the second is 72° (18*4)
Hope this helps
Answer:
Step-by-step explanation:
(1, 2) (2, 7)
(7-2)/(2 - 1) = 5/1= 5
y - 2 = 5(x - 1)
y - 2 = 5x - 5
y = 5x - 3

Answer:
47 / 48
Step-by-step explanation:
Quotient of 3/8 and 2
3/8 ÷ 2
3/8 * 1/2
= 3 /16
1 3/4 * 8/12
7/4 * 8/12
= 56/48
56/48 - 3/16
L. C. M of 48 and 16 = 48
(56 - 9) / 48
= 47 / 48
