10x=-80 I could us some hlp

lara31 [8.8K]

10x = -80

Note the equal sign. What you do to one side, you do to the other.

Divide 10 from both sides

10x/10 = -80/10

x = -80/10

x = -8

-8 is your answer for x

Prove sum of interior angle triangle is 180

ryzh [129]

Given :- 

A triangle ABC .

To prove :- 

Sum of interior angles of a ∆ is 180° .

Construction :-

Draw a line MCN parallel to AB .
Extend line AB to K .

Proof :- 

In ∆ ABC , we have ,

$\angle$ BAC + $\angle$ BCA = $\angle$ CBK

As sum of two interior angles of a triangle is equal to the opposite exterior angle .

Also ,

$\angle$ ABC + $\angle$ CBK = 180°

( linear pair )

Hence from above two ,

$\angle$ ABC + $\angle$ BAC + $\angle$ ACB = 180°

Hence Proved !
