Consider the picture below. find the measure of ∠.

image below v

leave step by step work

5º

Step-by-step explanation:

honestly im not sure if this will be right but i will try

since the triangles are i think the word is congruent, they equal the same

so 14x + 7 = 12x + 17

subtract 7 from both sides of the equal sign

and the equation is now 14x = 12x + 10

then subtract 12x from both sides of the equal sign

and now the equation is 2x = 10

divide both sides by 2

and x = 5

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
