Find the value of x.

x=75

Step-by-step explanation:

you have to 140 and the other side doesn't have anything so you take 180 and subtract it by 140 180-140=40 so the inside angle is 40 and since you have two angles in the triangle you add them then subtract it by 180 180-(40+35)=105 so now you have the last angle for the inside so then you subtract that angle to get x 180-105=75 so 75=x

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
