In the diagram to the right, arc QT = 140° and m P= 40°. If are QR = TS, what is the measure of arc TS?

answer: check all that apply, where the options?

step-by-step explanation:

answer: the answer is ann

x = 3 ± √(5+y)

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
