Answer:
22.43 units
Step-by-step explanation:
we know that
The perimeter of a polygon is the sum of its length sides
the formula to calculate the distance between two points is equal to
we have
u(-2,4),v(3,4) and w(3,-4)
step 1
Find the distance uv
substitute the values
step 2
Find the distance vw
substitute the values
step 3
Find the distance uw
substitute the values
step 4
Find the perimeter
Answer:
3x+4=40
Step-by-step explanation:
Lets take "x" as the number of students who went on the trip last year
It says "3 times" the number of seventh grade students that went on the trip last year so we know that x will be multiplied by 3
It also says 4 more than so we know that 3x+4 is gonna be part of the equation
If 40 students went on this years trip then 3x+4=40
Answer: 23 in
Step-by-Step Explanation:
Height (h) = 18 in
Base (b) = ?
Area (A) = 207 sq. in
We know,
Area of a Triangle = 1/2 * b * h
Therefore,
1/2 * b * h = 207
1/2 * b * 18 = 207
b * 9 = 207
9b = 207
b = 207/9
=> b = 23
Base (b) = 23 in
Answer:
74.2
Step-by-step explanation:
since 43.3 and 30.9 together form a vertical angle of k. So 43.3 +30.9= 74.2.
