Question

find the angle measure X in the following ​

Answer 1

$\huge\tt\colorbox{plum}{Answer}$

The sum of three angles of triangle is 180°

A = 40°

B = 90°

C = ?

Let the unknown degree C be 'x'

A + B + C = 180°

40° + 90° + x = 180°

130° + x = 180°

x = 180° - 130°

x = 50°

So, the another angle is 50°

Answer 2

Answer:

50 degrees

Step-by-step explanation:

Given Values:

A = 40 Degrees

B = 90 Degrees

C = ?

let C be equal to 'x'

40 degrees + 90 degrees = 130 degrees

Sum of all angles in a triangle  = 180 degrees

So, 180 - 130 = 50 degrees

Therefore, x = 50 degrees
