3(x+4)-10 = 1/10 (4x+16)
3x+12-10 = 1/10*2 (2x+8)
3x+2 = 1/5* (2x+8)
3x+2 = 2/5x + 8/5
15x+10 = 2x+8
15x-2x=8-10
13x = -2
x = -2/13

PLS SOMEONE HELP PLSSS
Sav [38]

Answer:

x=17

Step-by-step explanation:

ok so since lines PR and RQ are congruent (we know because of the lines on them), that means angles P and Q are also equal.

now we can set up the equation to find x like this:

29+29+(8x-14)=180 (180 because the three angles of a triangle always equal 180)

x=17
