Question

two angle of a triangle measure 30 and 55

Answer 1

Heya,

Solution to your question is:-
_______________________________

We know that,
In a ∆, sum of measure of all three angles is equal to 180°

Given, angle 1=30° and angle 2=55°.
Let third angle be "x°"

So, angle 1+angle 2 + x =180°
=>30+55+x=180
=>x=180-(30+55)
=>x=180-85
=>[x=95°] ANSWER...

Answer 2

HELLO MY DEAR FRIEND

THE 1ST ANGLE = 30 DEGREES 
THE 2ND ANGLE = 55 DEGREES
THE 3RD ANGLE = ?

HERE, WE HAVE TO USE THE TRIANGLE FORMULA 

= THE SUM OF ALL THE ALL THE TRIANGLES = 180 DEGREES.
= A+B+C = 180 DEGREES.

LET US TAKE THE THIRD ANGLE AS = X

= 30 DEGREES + 55 DEGREES + X DEGREE= 180 DEGREES.
=30+55= 85
=180-85 = 95
----------------
   X = 95 
----------------

THEREFORE, THE THIRD ANGLE = 95 DEGREES.

I HOPE THIS WILL HELP'S U............8-8
