Quadrilateral ABCD is inscribed in a circle. Angle B measures 74 degrees, and angle D measures (x-15) degrees. What does x equal? A-106
B-105
C-91
D-121

121degrees

Step-by-step explanation:

For a quadilateral inscribed in a circle, the sum of its opposite angles is 180degrees. Hence;

<B + <D = 180

x -15 + 74 = 180

x + 59 = 180

x = 180 - 59

x = 121 dgrees

Hence the value of x is 121degrees

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
