Answer:
x = 34 (btw my friend helped me with this one)
Explanation:
X+(3X+r)+R=180 right? Basic math (r is the small angle that form up PSR with 3X, R is just angle SRP)
x+(3X+r)+R=180
Put that to aside, next we have (3x+r)+T=180(T being TSP) yes?
But T+4x also=180
=>4x+(3x+r)
Next we have 68+3x+R=180 (smaller triangle)
Now we have all that, cramp them all together
We have two equations 68+3x+R=180 and x+(3x+r)+R=180
But 4x=3x+r sooo
Now we have 68+3x+R=180 or 3x+R=180-68
And 4x+x+R=1800 or 5x+R=180
Use the formula that i dont know the name of and calculate
x= 34 and R=10 how to check? 3x+R+68=3*34+10+68=180
