What is the area of the triangle below?

Step-by-step explanation: first you have to add 5 and 5 which is 10 and then add 8 which = 18 or if its timesing its 5 times 5 = 25 and 25 times 8 = 200 hope it helps ( the answer is probably the adding one kk)

By the angle addition postulate, the size of angles RQS and TQS must sum to three angle TQR. S once angle TQR is a straight angle it measures 180°

6x+20+2x+4=180
8x+24=180
8x=156
x=39/2

angle TQS measures 6*(39/2)+20=137°
angle QSR measures 2*(39/2)=43°

if you add these you'll see they do sum to 180
