The answer is B. 4
Rewrite the logarithmic equations using exponential equation
x- 3 / 2 = 1 / 8
The above equation may be rewritten as
x - 3 / 2 = 1 / 23 = 2-3
(√x)-3 = 2-3
The above equation gives
√x = 2 or x = 4
Let the length of string A be x
it is 1 yard = 3 ft shorter than string B
so length of string B = x+3
String C is 1ft 8 inches shorter than B,
so C = x+ 1ft 8 inch = x+ 1+ 2/3 ft.
Total of A +B+C = 13ft 4inch = 13 + 1/3 ft.
x + x+3 + x+1+2/3 = 13 + 1/3
3x + 4 + 2/3 -1/3 = 13
3x = 13 - 4- 1/3
3x = 9 -1/3
x = 3 -1/9
x = 3ft - 12/9 inches = 3 ft - 4/3 inches
x = 2.889 ft
You need to know what type of triangle it is , all your triangles are right angles that means that they are 90° so you just need to subtract the number that its given from 90° ex
the first problem you just have to do this
21° - 90° = 79 °
so x = 79°
Approximately 14%
14-12=2
2/14=1/7
1/7*100=14.29
14.29%
let me tell u I don't know so give me an complete thuought
