Answer:
∠ ADC = 53°
Step-by-step explanation:
Note the angle between the radius and the tangent is 90°
The sum of the angles in quadrilateral AOCB = 360°, thus
∠ AOC = 360° - (90 + 90 + 74 )° = 360° - 254° = 106°
∠ AOC is twice the angle on the circumference ∠ ADC, thus
∠ ADC = 106° ÷ 2 = 53°

Answer:
B. dp = k
Step-by-step explanation:
The statement of variation is ...
d = k(1/p) . . . . days vary inversely with p
Multiplying by p gives ...
dp = k
sum of the triangle angles are 180°
A+80+39=180°
A=180°-119°
A=61°
