If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m

nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

$2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17$

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

$\angle1=2(17)+6\\\angle1=34+6\\\angle1=40$

So, the actual measure of ∠1 = 40°

Simplify.<br><br> 1/2b - 2/5b<br><br> please i am begging u

DerKrebs [107]

First, we need to find the LCD (Least Common Denominator) so we can subtract them much easier.

An easy way to find the LCD is to just multiply the denominators together: So 2 • 5 = 10

We have to do the same to the numerators too though.

1/2 (5) = 5/10

2/5 (2) = 4/10

Now, the remade expression is:

5/10 - 4/10 which will equal 1/10.

Hope it helped! If it did, please mark as Brainliest! :)
