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
You will have to find what x is to get your answer solve each to find the answer
153 000 = 100 000 + 50 000 + 3 000
The first one is 2.78% second one is 3.8% third one is 4.5% and it will be 378
