Answer:

60 degrees

Step-by-step explanation:

The measure of an inscirbed angle is half the measure of the intercepted arc.

(The measure of the arc is twice the measure of the angle!)

The inscribed angle at V intercepts an arc of 2 x 119 = 238 degrees, so the measure of arc FGH is 238. Subtract arc GH from that, 238 - 168 = 70, so that is the measure of arc FG.

The angle at H intercepts an arc with measure 2 x 65 = 130. The measure of arc VFG is 130. But arc FG is part of that, so subtract its measure from 130. 130 - 70 = 60.

The measure of arc FV is 60 degrees.

Answer:

FV = 60

Step-by-step explanation:

VG => 65 × 2 = 130

FH major arc=> 119 × 2 = 238

FH major arc - GH = FG

FG => 238 - 168 = 70

VG - FG major arc = FV

FV => 130 - 70 = 60

Answer:

A) 53

B) 53%

C) 37%

D) 63%

E) Yes.

Step-by-step explanation:

A) 53 people did not get headaches at all.

B) To solve for the percentage of participants that reported they did not get a migraine headache, you will need to divide out of the TOTAL number of people:

53/100= .53 --> Convert to percentage--> .53×100 = 53%.

C) To find this value, you will need to divide out of the amount of people that took MEDICINE and got a headache:

22/60≈0.367--> Convert to percentage --> 0.367×100≈37%

D) This percentage will be found out of who did NOT take the medicine:

25/40= 0.625 --> Convert to percentage --> 0.625×100≈63%

E) The medicine did help prevent migraine headaches because the percentage that got migraines with the medicine is lower than the percentage that got migraines WITHOUT the medicine.

It would be 90%..... 45/450= 10%.... so there would be 90% not being used.
