Pls dolve this all please fast urgent

Answer 1

HELLO MY DEAR FRIEND

1ST SOLUTION - LET US TAKE A,B AND C.

                             THE VALUE OF A = 60 DEGREES 
                              THE VALUE OF B = 50 DEGREES
                              THE VALUE OF C = ?

HERE WE HAVE TO USE THE SUM OF TRIANGLE FORMULA 

= THE SUM OF ALL SIDES OF A TRIANGLE = 180 DEGREES 

= A + B + C = 180 DEGREES.
= 60 DEGREES + 50 DEGREES + C DEGREE = 180 DEGREES.
= 60 DEGREES + 50 DEGREES = 110 DEGREES.
= 180 DEGREES - 110 DEGREES = 70 DEGREES 
THEREFORE, THE VALUE OF THE C = 70 DEGREES.

2 ND SOLUTION - THE VALUE OF THE 1ST ANGLE = 43 DEGREES.
                               THE VALUE OF THE 2ND ANGLE = 90 DEGREES
                               ( THE VALUE OF 2ND ANGLE IS 90 DEGREES                                                BECAUSE THE 2ND ANGLE IS RIGHT ANGLE. SO WE
                                  CAN SAY THAT 2ND ANGLE = 90 DEGREES).
                                  THE VALUE OF THE 3RD ANGLE = ?

LET US TAKE 1ST ANGLE = A
2ND ANGLE = B
3RD ANGLE = C

HERE WE HAVE TO USE THE SUM OF ALL SIDES OF A TRIANGLE FORMULA.

= THE SUM OF ALL SIDES OF A TRIANGLE = 180 DEGREES.
= A+B+C = 180 DEGREES 
 = 43 DEGREES + 90 DEGREES = 133 DEGREES 
 = 180 DEGREES - 133 DEGREES = 47 DEGREES
THEREFORE, THE C = 47 DEGREES.

3RD SOLUTION - LET US TAKE A, B , C
                             A =123 DEGREES 
                             B =48 DEGREES 
                             C = LET'S TAKE X DEGREE 

SUM OF ALL SIDES OF A TRIANGLE = 180 DEGREES.
= A + B + C = 180 DEGREES 
123 + 48 = 171 
= 171 - 123 = 9 DEGREES 
THEREFORE THE C = 9 DEGREES

5 TH SOLUTION - A = 73 DEGREES 
                               B =65 DEGREES
                               D = ?

THE SUM OF ALL SIDES OF A TRIANGLE = 180 DEGREES
= A + B + D = 180 DEGREES
= 73 + 65 = 138 DEGREES
= 180 DEGREES - 138 DEGREES = 42 DEGREES
THE VALUE OF C = 42 DEGREES.

6TH SOLUTION - A = 23 DEGREES 
                             B = 38 DEGREES 
                             C =?

SUM OF ALL SIDE OF A TRIANGLE = 180 
A + B + C =180 
23 + 38 = 61 DEGREES
= 180 DEGREES - 61 DEGREES = 120 

THEREFORE THE C = 120 DEGREES.
