What is the value of x?<br><br> Enter your answer in the box.<br><br> x = <br><br> I NEED HELP ASAP
melomori [17]

The sum of the angles of a triangle is 180°. So you can do:

91° + (8x + 3)° + (10x - 4)° = 180°   To find x, you need to isolate/get the variable "x" by itself in the equation. First combine like terms (terms that have the same variable and power/exponent]

91 + 3 - 4 + 8x + 10x = 180      (I rearranged for the like terms to be next to each other)

90 + 18x = 180      Subtract 90 on both sides

18x = 90       Divide 18 on both sides to get "x" by itself

x = 5

PROOF

91° + (8x + 3)° + (10x - 4)° = 180°       Plug in 5 for "x"

91° + (8(5) + 3)° + (10(5) - 4)° = 180°

91° + (40 + 3)° + (50 - 4)° = 180°

91° + 43° + 46° = 180°

180° = 180°
