Answer:
Option 3rd is correct
the sum of the interior angles measures in a 22-gon is, 3600°
Step-by-step explanation:
Sum of the interior angles of a polygon of n -sides is given by:
....[1]
As per the statement:
Given that:
n = 22-gon
Substitute in [1] we have;
⇒
⇒
Therefore, the sum of the interior angles measures in a 22-gon is, 3600°
Answer:
Consider the given vectors.
a=3i+2j−6k
b=4i−3j+k
Now,
a⋅b=(3i+2j−6k)(4i−3j+k)
a⋅b=12−6−6=0
Therefore,
Two vectors a and b are perpendicular.
Thus, the angle between the vectors a and b =90∘
Hence, this is the answer.
Step-by-step explanation:
I really hope this help you:)
if not I'm sorry:(
Ok to figure it out you first find the common factor, which is 12
so the fractions become 8 3/12 and 10/12 then you subtract those 2,
8 3/12-10/12 is 7 5/12.
Hope That Helps!!!
Answer:
254 yds²
Step-by-step explanation:
There are 6 faces of the prism we need to calculate the area of for a rectangular prism.
The base and top of the prism measure 9x7 yards each, so there are two faces with an area of 63 yds² (9 x 7 = 63)
The sides of the prism measure 4x7 yards each, so there are two faces with an area of 28 yds² (4 x 7 = 28)
The front and back face of the prism measure 9x4 yards each, so there are two faces with an area of 36 yds² (9 x 4 = 36)
The total surface area is
2(63) + 2(28) + 2(36) = 254 yds²
