I need this problem solved real quick

PIT_PIT [208]

Let's take this problem step-by-step:

The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'

⇒ is on a straight line

⇒ sum of angle measure = 180 degrees

$unlabeled_.angle+78 = 180\\unlabeled_.angle = 102$

Now we know:

⇒ sum of all angles in a triangle ⇒ 180°

Let's put that in equation form and solve:

$x + 102 + 57=180\\x + 159=180\\x = 21$

Answer: 21°

Hope that helps!

Jerome tries to find the value of the expression 3 - 6 + 5 by first applying the commutative property he rewrites the expression

Lana71 [14]

Wrong in sign change

How?

In commutative law the sign doesn't change whenever it is applied.

Thus

$\\ \sf{:}\implies 3-6+5$

$\\ \sf{:}\implies 3\underline{+5-6}$

$\\ \sf{:}\implies 8-6$

$\\ \sf{:}\implies 2$
