The answer for your answer is (x+3)(2x+7)
2y+x-2y+3x=180
x=45
2x-15=-2y+3x
y=30
-3*-2=6+3=9 you got that part right
3*-4=-12+9=-3
therefore 9>-3
743.476 < 743.746
743.746 > 743.476
It’s an isoceles triangle so 180-64=116degrees = the sum of the other two equal angles in the triangle QRP and so angle QRP is 116÷2=58degrees, angles QRP and SRT are vertically opposite so they’re equal. The triangle SRT is also isosceles so 180-58= 122degrees = the sum of the last two equal base angles (including RST that you want to find) So lastly do 122÷2= 61degrees = angle RST
