Question

Find the value of x in the following figure.​

Answer 1

Answer:   HI

Step-by-step explanation:  ANSWER

SO WE SOLVE THIS SUM BY USING THE ANGLE SUM PROPERTY

ANGLE SUM PROPERTY STATES THAT THE SUM OF ALL ANGLES OF A TRIANGLE IS EQUAL TO 180

SO,

X+X+42 = 180 ( ANGLE SUM PROPERTY )

2X = 180 - 42

2X = 138

X = 138 /2

X =  69

FOR CHECKING THE ANSWER :

WE PLUS ALL THE ANGLES

69 +69+ 42 = 180

HOPE IT HELPS !

$\bf\implies x+x+42° \longrightarrow 180°$

$\bf\implies 2x+42° \longrightarrow 180°$

$\bf\implies 2x \longrightarrow 180°-42°$

$\bf\implies x \longrightarrow \frac{138}{2}$

$\bf\implies x \longrightarrow 69°$

$\bf\implies\boxed{x \longrightarrow 69°}$
