Answer:
∠ PQR = 70°
Step-by-step explanation:
The tangent- tangent angle PQR is half the difference of the intercepted arcs.
minor arc PR = 360° - 250° = 110°
Then
∠ PQR =
(250 - 110)° =
× 140° = 70°

Answer:
C
Step-by-step explanation:
Step-by-step explanation:
We know that...
x+y (from the first pair) corresponds to 8(in the second pair)..
0 (from the first pair) corresponds to x-y (in the second pair)..
Hence,

By simply adding the two equations we get,

Hence,
By substituting x=4, we get that y=4
Hence,
x=y=4
