Answer:
The distance around the inside is 199.44 m.
Step-by-step explanation:
Given that,
Length = 84.39 m
Width = 9.76 m
Suppose, all the way around and 73 m wide.
We know that,
Perimeter of half circle is
We need to calculate the inner radius of the circle
Using formula of radius
Put the value into the formula
We need to calculate the distance around the inside
Using formula of distance
Distance around the inside= two inner perimeter of the circle+two length of rectangle
Put the value into the formula
Hence, The distance around the inside is 199.44 m.
Answer:
a) x value is -2, min is -3(if thats y)
b) x value is 3, max is 21(if thats y)
Step-by-step explanation:
yes you do quadratic formula and such :)
Its adding the current number by the previous number so the next three would be 21,34,55
Answer:
1=20
Step-by-step explanation:
40 divided by 2 is 20 so
1=20
Answer:
145°
Step-by-step explanation:
There are a couple of ways you can get there:
1. ∠ACB is a right angle, 90°. Hence, ∠BAC is the complement of ∠ABC, so is ...
... ∠BAC = 90° -∠ABC = 90° -55° = 35°
Then, ∠BAC and ∠BAD are a linear pair, so total 180°. That makes ∠BAD the supplement of ∠BAC, so ...
... ∠BAD = 180° -35° = 145°
2. ∠BAD is the exterior angle at A for the triangle ABC. It will have a measure that is the sum of the opposite interior angles: given ∠ABC = 55° and right angle ACB = 90°.
... ∠BAD = 55° +90° = 145°
