Which equation correctly describes the relationship between the measures of the angle and arcs formed by the intersecting secants? m∠1=12(mPQ−mRS) m∠1=12(mPQ+mRS) m∠1=mPQ−mRS m∠1=12mRS Circle with two chords. Point P at 1 o clock, point Q at 5 o clock, point S at 8 o clock, and point R at 9 o clock are on the circle. Segment P R and segment Q S intersect each other outside the circle. The angle made at the intersection point is labeled as 1.

If you can solve all of these i will give ! - 4% of 190 - 4% of 162.5 - 4% of 140 - a 4% increase from 155.1 - a 4% increase from 159.8

`if you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain. ''.

Aresearch study is studying the effects of a new drug for osteoporosis alzheimer's disease (ad) for women above the age of 65 years. a group of individuals with osteoporosis is randomized into two groups. one group is treated conventionally, and the second group is treated with the new medication. assessments are made at 3, 6, 12, 36, and 48 months. the conventionally treated group is assessed for ad using a serum blood test, and the treatment group is assessed for ad using a pet radiotracer that binds to beta-amyloid plaques. in comparing these 2 trial arms, the authors of the study may encounter which type of bias? a. selection bias on the risk of developing b. measurement bias c. confounding bias d. recall bias e. lead-time bias
