Answer: The coordinates of D are Option c (1,-2)

explanation:

The Parallelogram is a quadrilateral whose opposite sides are equal and parallel. The location of a parallelogram on a coordinate plane is determined based on its four vertices.

A coordinate plane is a two-dimensional plane formed by the intersection of two lines one is a vertical line and the other is horizontal. The vertical line is the y-axis and horizontal line x-axis.

Four points of parallelogram ABCD are A(-2,4),B(1,3), C(4,-1), D(1,-2)

In the diagram of circle R, m FGH is 50. what is mFEH

garri49 [273]

Options

130°
230°
260°
310°

Answer:

(B) $m\angle FEH=230^\circ$

Step-by-step explanation:

We know that the External Angle = Half the Difference of the Two Arcs

Therefore:

Since FGH is the exterior angle and FEH and FH are the two arcs, then:

$\dfrac12 (\angle FEH-\angle FH)=50^\circ\\\\\angle FEH- \angle FH=100^\circ$

Also:

$\angle FEH+ \angle FH=360^\circ$

Adding the two equations, we have:

$\angle FEH- \angle FH+(\angle FEH+ \angle FH)=360^\circ+100^\circ\\2\angle FEH=460^\circ\\$Divide both sides by 2\\Therefore\\m\angle FEH=230^\circ$

WILL GIVE BRAINLIEST (Right angle) Trigonometry please help!

nirvana33 [79]

Answer:

<A = 41.4°

Step-by-step explanation:

Recall, SOH CAH TOA

Reference angle = <A

Hypotenuse length = 8

Adjacent length = 6

Since Hypotenuse and Adjacent are involved, we would apply CAH, which is:

Cos A = Adj/Hyp

Plug in the values

Cos A = 6/8

Cos A = 0.75

$A = Cos^{-1}(0.75)$

A = 41.4096221° ≈ 41.4° (nearest tenth)

Which of the following equations have the same solution as the equation 3x+2y=-12 ? Check all that apply.

juin [17]

If one equation is the same, there is a multiply factor:

f*(3x+2y)=f*(-12)

You need to find the same factor for both members.

3x-2y=12. This is not the same.

-3x-2y=12. This is the same. The factor is (-1)

15x+10y=-60. This is the same. The factor is 5.

6x+2y=-12. This is not the same.

6x+4y=-24. This is not the same.

1.5x+y=-6. This is the same. The factor is 1/2.

x+ 2/3y=-12. This is not the same.

Good luck!
