If the following shape is 90 degrees it should be consider a right triangle
Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
Answer:
Step-by-step explanation:
Perimeter = 2(l + w)
Perimeter = 464inches
Length l = 100inches
: 464 = 2(100 + w)
Dividing be 2
464/2 = 100 + w
232 = 100 + w
Collecting like terms
232 - 100 = w
132 = w
It is 132 inches long
When the exterior sides of two adjacent angles form a straight line or in this case form an opposite ray then, the angles are supplementary. The supplementary angles are those whose sum of the measures is 180°. Thus, the answer to this is letter B.
