Answer:
(5, -1)
Step-by-step explanation:
Midpoint = (x1 + x2 ÷ 2) , (y1 + y2 ÷ 2)
MP= (7 + 3 ÷ 2), (-5 + 3 ÷ 2)
= (10÷2), (-2÷2)
=(5), (-1)
MP= (5, -1)
Answer: Option C.
Step-by-step explanation:
The coordinates (x,y) of a terminal point for an angle θ are:
x = cos(θ) and y = sin(θ).
In this case, we have θ = 330°.
Then we have:
x = cos(330°) = 0.866 = (√3)/2
y = sin(330°) = -0.5 = -1/2
then the coordinates of the terminal point are ((√3)/2, -1/2)
Then the correct option is c.
Answer:
Step-by-step explanation:
Supplementary angles means that the angle sum of the two angles will equal 180 degrees :)
Answer:
A)(7,-9)
Step-by-step explanation:
we know x=7
so put it in the equation
y= -2(7)+5
y=-9
we always put the x coordinate first and then the y coordinate so the answer is (7,-9)
By the Pythagorean theorem
.. 15^2 = 10^2 +a^2
.. 225 = 100 +a^2
.. 125 = a^2
.. √125 = a
.. 5√5 = a ≈ 11.18
The missing side length is 5√5 cm.
