Question

Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x.

Answer 1

Answer:

34.5

Step-by-step explanation:

An easy way to find this out is plug in all the answers into our equation until we get 180. So here's what you do:

A) X=25.5

So put that in the equation replacing x like this :  2(25.5)-9 =42 then multiply by three which = 126, So, A) is not our answer, now do it with the rest until you get 180,

2(34.5)-9=60 60x3=180 so your answer will be the number you plug in aka:34.5

Hope this helps you understand the topic a little better <3

Answer 2

Answer:

x = 69

Step-by-step explanation:

Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x. O A. x = 60 O B. x = 25.5 O C. x = 69 O D. x = 34.5

im not 100% sure about this but i think i did this right hope it help man!
