Question

in angles of the Triangles are(x+21),x and (2x-45), find the value of x​

Answer 1

Step-by-step explanation:

We know angle sum property of a triangle is 180° x+21 + x + (2x-45) = 180° 2x + 21 + 2x

Answer 2

$\huge\red{A}\pink{N}\orange{S} \green{W}\blue{E}\gray{R} =$

We know angle sum property of a triangle is 180°

x+21+ x + (2x-45) = 180°

2x+21+ 2x - 45 = 180°

4x 24 = 180°

4(x - 6) = 180°

x - 6 = 180°/4

x - 6= 45

x = 45 + 6

x = 51°

Therefore x = 51°

(x+21) = 51 +21= 72°

(2x - 45) = 2 x 51-45= 102-45 = 57°

Angles of triangle are 51°, 57° and 72°.
