Answer:

Below.

Step-by-step explanation:

a + b + c = 180 degrees (angles in a triangle)

c + d = 180 degrees ( adjacent angles).

So, subtracting the 2 equations:

a + b + c - c - d = 0

a + b - d = 0

a + b = d.

What is the answer to this problem -2x – 4 < 3x + 21

horsena [70]

Start with

$-2x-4 < 3x+21$

Add 2x to both sides:

$-4 < 5x+21$

Subtract 21 from both sides:

$-25 < 5x$

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

$-5 < x$

So, the answer is $x > -5$
