Answer:
2.3 cm if that's an option. Not sure tho
Step-by-step explanation:
Pls mark as brainliest
Answer: Choice C)40cm
Step-by-step explanation:
We know that cosp=0.6 and PM=24 so,
PM/PN=0.6
24/PN=0.6
by rearranging we get
PN=24/0.6
PN=40
Answer:
16.24 Units
Step-by-step explanation:
The perimeter of the triangle is the sum of the length of the sides of the triangle. Given the points on the vertices, the length of each side may be found using the formula
Length = √(x2 - x1)^2 + (y2 - y1)^2
Considering the pair (-1, 2), (3, 1), the length of that side
= √(3 -- 1)^2 + (1-2)^2)
= √(16 + 1)
= √17 units
Considering the pair (-1, 2), (7, 2), the length of that side
= √(7 -- 1)^2 + (2-2)^2)
= √(64)
= 8
Considering the pair (3, 1), and (7, 2), the length of that side
= √(7 - 3)^2 + (2 - 1)^2
= √(16 + 1)
= √17
Hence the perimeter of the triangle
= √17 + 8 + √17
= 4.12 + 8 + 4.12
= 16.24 Units
I won't bore you with the details, but according to my math the answer should be C. 1/2.
