The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.
In the given question, the two angles are complementary Angle pair, so the sum of their values will add up to 90°
that is ~

Answer:
60 meters, see explanation.
Step-by-step explanation:
We know that the ratio of length : width is 10 : 6. So for every 10 meters of length, we also have 6 meters of width. This problem is much easier since we are given the P = 160 meters.
You can see that if we multiply the ratio by ten, we get 100 : 60, where 100 + 60 = 160 total meters. From here, it is clear that the width would be 60 meters.
Answer:
Length in feet = X - 80
Step-by-step explanation:
A = width x length
A/width = length
(x^2 -100x + 1600) /( x - 20) = length
(x - 20) (x - 80) / (x - 20) = length
x - 80 = length
x - 80 = length
