(4/7)-(1/3)
(12/31)-(7/21)
(5/21) is left
Or
In decimal form
(4/7)=0.571
(1/3)= 0.333
0.571-0.333
=0.238
8 and 32.
8 times 4 = 32
32 - 8 = 24
4x - x = 24.

Answer:
The length of the missing side x = 47.57 in
Step-by-step explanation:
Given
Ф = 28°
The length of the side adjacent to the angle Ф is = 42 in
To determine
The hypotenuse x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
substitute adjacent = 42 in, hypotenuse = x and Ф = 28°
cos 28° = 42 / x
x = 42 / cos 28°
x = 47.57 in
Therefore, the length of the missing side x = 47.57 in
Step-by-step explanation:
because angle A and C are similar, so
9x-8=28
9x=36
x=4
