Find the value of x.

From the figure,

(19x+3) =( 11x-2) + (9x+1){ exterior angle of a triangle is equal

to the sum of 2 opposite interior angles}

now,

19x+3 = 11x-2 + 9x+1

19x-20x = -2+1-3

-x = - 4

therefore,

X = 4.

if you want to find the value of angles ,

just put 4 Inthe place of X.

and do ..

.Do you know a Unkn

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

true
