Answer:
28
Step-by-step explanation:
substitute the value of the variable into the expression and simplify
The exterior angles of a triangle are (2x+10)⁰, (3x-5) ⁰ and (2x+40) ⁰
To get interior angle for each , subtract from 180
![180-(2x+10)=170-2x\\180-(3x-5)=185-3x\\180-(2x+40)= 140-2x](https://tex.z-dn.net/?f=180-%282x%2B10%29%3D170-2x%5C%5C180-%283x-5%29%3D185-3x%5C%5C180-%282x%2B40%29%3D%20140-2x)
Sum of interior angles = 180
![170-2x+185-3x+140-2x=180](https://tex.z-dn.net/?f=170-2x%2B185-3x%2B140-2x%3D180)
![-7x+170+185+140=180\\-7x+495=180\\-7x+495-495=180-495\\-7x=-315\\x=45](https://tex.z-dn.net/?f=-7x%2B170%2B185%2B140%3D180%5C%5C-7x%2B495%3D180%5C%5C-7x%2B495-495%3D180-495%5C%5C-7x%3D-315%5C%5Cx%3D45)
![170-2x=170-2(45)=80\\185-3x=185-3(45)=50\\140-2x=140-2(45)=50](https://tex.z-dn.net/?f=170-2x%3D170-2%2845%29%3D80%5C%5C185-3x%3D185-3%2845%29%3D50%5C%5C140-2x%3D140-2%2845%29%3D50)
Answer: x=45
smaller angle =50 degree
largest interior angle = 80 degrees
Answer:
47 feet per second
Step-by-step explanation:
35+(40X5)=235
235/5=47 feet per second
(47 feet per second is aproximately 32 mph.)
