Hello!

Since the angles are alternate interior angles they equal each other

5x - 28 = 3x + 12

Now you solve this algebraically

5x - 28 = 3x + 12

Subtract 3x from both sides

2x - 28 = 12

Add 28 to both sides

2x = 40

Divide both sides by 2

x = 20

Now we put x into the equation we are wanting to find out

5x - 28

5(20) - 28

Multiply

100 - 28

Subtract

72

The answers are x = 20 and 5x - 28 = 72°

Hope this helps!

16 m, 21 m, 39 m in geometry tryna find out how to measure the side length that could form a triangle
Lera25 [3.4K]

Step-by-step explanation:

The given measurements are:

16 m, 21 m, 39 m

We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.

\therefore \: 39 + 21 = 60 > 16 \\  \\  \:  \:  \:  \:  \:  \: 16 + 39 = 55 > 21 \\  \\  \:  \:  \:  \:  \:  \: 16 + 21 = 37   \ngtr39 \\  \\  \because \: last  \: mathematical\: statement \: is  \:\\ defying \: the \: above \: law \\

Therefore, it is not possible to form a triangle with given measurements.
