Will give extra points to whoever solves this

Hatshy [7]

Answer:

Step-by-step explanation:

As Angle 5 and Angle 4 form a linear pair, they are supplementary.

Hence,

$Hence,\\Angle\ 5\ +\ Angle\ 4\ =\ 180\\(3x+7)+(9x-43)=180\\12x+(-36)=180\\12x=180+36\\12x=216\\x=18\\\\Hence, Obtuse\ Angle\ UPS = Angle\ 4 + 90\\Hence,\\Obtuse\ Angle\ UPS\ = (3x+7)+90\\\\We\ know\ that\ x=18 \\Hence, Angle\ 4\ = (3*18+7)\\=(54+7)\\=61\\\\Obtuse\ Angle\ UPS\ = 61+90\\=151\\\\\\Reflex\ Angle\ UPS\ = 360-151\\=209$

How to slove this: x-5/3=x-3/5

sladkih [1.3K]

Answer: There are no solutions.

Step-by-step explanation: x - 5/3 = x - 3/5

x + -5/3 = x + -3/5

x + -5/3 - x = x + -3/5 - x

-5/3 = -3/5

-5/3 + 5/3 = -3/5 + 5/3

0 = 16/15
