C) is the answer i believe hope it helps have a good day
For the given triangle, x = 16 units.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is 60°. The adjacent side has a length of 8 units while the hypotenuse of the triangle measures x units. To calculate the cos of angle A we divide the length of the adjacent side by the length of the hypotenuse.
cos A
Step 2:
The length of the adjacent side = 8 units.
The length of the hypotenuse = x units.
So the hypotenuse of the given triangle measures 16 units. x = 16 units which is the third option.
F(-1)....this is basically saying that x = -1...and when x = -1 (according to ur chart), then f(-1) = 0 <==
The formula for perimeter of a triangle is P = a + b + c, where a, b, and c are the side lengths of the triangle. Since the sides of this triangle are consecutive numbers, they can be represented as follows.
a = a
b = a + 1
c = a + 2
The perimeter is known, so plug these values into the formula to find a.
P = a + b + c
48 = a + (a + 1) + (a + 2)
48 = a + a + 1 + a + 2
Collect like terms.
48 = 3a + 3
Subtract 3 from both sides.
45 = 3a
Divide both sides by 3.
15 = a
Calculate a + 1 and a + 2 by substitution to find the other two side lengths.
15 + 1 = 16
15 + 2 = 17
Answer:
The side lengths of the triangle are 15, 16, and 17.
