Answer:
(-4, 3)
Step-by-step explanation:
This is an increase of 8 in the y coordinate, so the answer is (-4, -5 + 8) or (-4, 3).
We can use sine to figure this out. Sine is opposite over hypotenuse.
So therefore:
sin(45°)=x/24
x=24sin(45)
x=12√2 or about 16.970
Answer:
(1) x=
−1
/2
y+
5
/2
(2)
x=
−1
/2
y−2
Step-by-step explanation:
<u>(1)</u> 2x+y=5
Step 1: Add -y to both sides.
2x+y+−y=5+−y
2x=−y+5
Step 2: Divide both sides by 2.
2x
/2
=
(−y+5)/2
x=
−1
/2
y+
5
/2
<u>(2) </u>Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.
−2x
/−2
=
(y+4)
/−2
x=
−1
/2
y−2
In this example, we are asked to find the perimeter of the trapezoid. The perimeter of a figure is the distance around the figure.
To find the perimeter of the trapezoid, all we have to do is add the lengths of the sides. In this case, we would add 3 + 5 + 3 + 9 = 20 cm.
<em>Therefore, the perimeter of the trapezoid is 20 cm</em>
