P, Q and R are points on a circle. A tangent to the circle, RT is also shown. What is the size of angle x? Give a reason for your answer. PS: I know the answer is 60, but I don't know how to write the reason for it.

Step-by-step explanation:

x = 60° { the angles formed by a tangent to a circle and a chord drawn from the point of contact are equal to respective angles in alternate segments }

Hope it will help

60

Step-by-step explanation:you add p plus q plus r which is 70+60+50 which equals 180 divided by 3 because p,q,and r and it equals 60. Hope I helped

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.
