What is the the value of x. Pleaseeeee help I’ll mark you brainlist pls don’t put any links

Answer 1

Answer:

x = 11.75

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

5x + 3x - 4 + 90 = 180

8x + 86 = 180 ( subtract 86 from both sides )

8x = 94 ( divide both sides by 8 )

x = 11.75
