Question

Two angles of a triangle are 72° and 38°. Find the third angle.(A) 103°
(B) 70°(C) 90°
(D) 54°

Answer 1

ANSWER IS HERE

The sum of the angles of a triangle is 180 degree.

Let the third angle be x.

72+38+x=180

110+x=180

x=180-110

BRAINLIEST ANSWER

x=70 degree(Option B)

Answer 2

here you go ☆☆

$\bold{ \underline{we \: know \: that}}$
sum of all angles of all triangle 180°

so, let us assume third angle be x.....

$72 + 38 + x = 180$

$111 + x = 180$
$x = 180 - 110$

$x = 70$
$\bold{ \underline{third \: angle = 70}}$
so correct option is (B)


$\boxed{hope \: it \: helps}$
