Step-by-step explanation:

In AGHI, GI is extended through point I to point J, mZGHI = (2x - 3)º,
mZIGH = (2x + 15)°, and m_HIJ = (7x – 18)'. Find mZGHI.

Answers

Answer:

m<GHI = 17°

Step-by-step explanation:

m<GHI = (2x - 3)°

m<IGH = (2x + 15)°

m<HIJ = (7x - 18)°

<HIJ is an exterior angle of ∆GHI

<GHI and <HIJ are both interior angles of ∆GHI that are opposite to the exterior angle.

Therefore, based on the exterior angle theorem of a triangle, we would have the following equation:

m<GHI + m<IGH = m<HIJ

(2x - 3)° + (2x + 15)° = (7x - 18)° (substitution)

Solve for x

2x - 3 + 2x + 15 = 7x - 18

Add like terms

4x + 12 = 7x - 18

4x - 7x = -12 - 18

-3x = -30

Divide both sides by -3

x = 10

✔️m<GHI = (2x - 3)°

Plug in the value of x

m<GHI = 2(10) - 3 = 20 - 3

m<GHI = 17°

Solve the inequality: x - 12 < -16

Answers

X< -4
You need to do inverse operations and add 12 to both sides.

Answer:

x > -4

Step-by-step explanation:

What you do is in order to get the x by itself you need to do the opposite of -12 which is just +12 so you need to add 12 to both sides. You should end up with something like this:

x -12 + 12 < -16 + 12

x < -4

So, that should be your answer. Hope this helps :) Have a good day!!

What is the measure of ∠1 plus the measure of ∠3 minus the measure of ∠2?

Answers

Answer: If 1 and 2 are adjacent right angles, they are both 90º.

1 and 3 are vertical, which means they must be congruent, so 3 is also 90º
