To find perimeter you must add all the side lengths together:
P = AB + BC + AC
The side lengths AC and BC are easy to find. You must simply count how many units they span. Please refer to the image below to see how I did this.
To find the length of AB is a bit trickier. Since the trianlge shown is a right trianlge you may use pythagorean theorem
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = 6
b = 7
^^^Plug these numbers into the theorem
solve for c
36 + 49 =
= 85
c ≈ 9.219
c ≈ 9.2 units
Hope this helped! Let me know if you have any further questions!

Answer:
The time taken for the flare to hit the ground is approximately 10.7 seconds.
Step-by-step explanation:
Given : Suppose a flare is shot from the top of a 120 foot building at a speed of 160 feet per second. The equation models the h height at t seconds of the flare.
To find : How long will it take for the flare to hit the ground?
Solution :
The equation models the h height at t seconds of the flare.
The flare to hit the ground when h=0.
Substitute in the equation,
Applying quadratic formula,
Where, a=-16, b=160 and c=120
Reject the negative value.
Therefore, the time taken for the flare to hit the ground is approximately 10.7 seconds.
Answer:
cosR =
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR = =
=
