Answer:
20 units
Step-by-step explanation:
Since the triangle is equilateral then all 3 sides are equal in length.
Equate any 2 sides and solve for x
4x = 3x + 5 ( subtract 3x from both sides )
x = 5
hence
4x = 4 × 5 = 20
3x + 5 = (3 × 5) + 5 = 15 + 5 = 20
7x - 15 = (7 × 5) - 15 = 35 - 15 = 20
The lengths of the sides are 20 units
Answer:
y = 17x - 55
Step-by-step explanation:
Convert the coordinates in point-slope form:
y + 4 = 17(x -3)
y + 4 = 17x - 51
Subtract 4 in both sides:
y = 17x - 55
Thanks!
Answer:
radical 1/2
Step-by-step explanation:
45-45-90 triangle
hyp= radical 1/2 (radical 2)
therefore x (median side aka)= radical 1/2
B) a=-1, b=5, c=0 would be the correct answer
Answer:
0.4476 degrees.
Step-by-step explanation:
Let θ be the angle between the beam and the road. The given values form a right triangle with the distance that the beam drops ( h=3 in) being the side opposite to θ and the distance in front of the car (x=32 ft or x=384 in) being the side adjacent to θ.
Therefore, θ is given by:
The angle between the beam and the road is 0.4476 degrees.
