Answer:the answere is 3/40 I hope this help
Step-by-step explanation:
Answer:
∠ XAZ = 50°
Step-by-step explanation:
The measure of the circle = 360°
Given arc XYZ = 230°, then
arc XZ = 360° - 230° = 130°
The tangent- tangent angle XAZ is one half the difference of the intercepted arcs, that is
∠ XAZ =
(230 - 130)° = 0.5 × 100° = 50°
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
A,C,D those were the answers i put and they were correct.
