Answer: 3 <em>7</em>/14 + 2 <em>12</em>/14 = 5 <em>19</em>/14
Step-by-step explanation:
Find the LCM of the denominator.
2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
7 = 7, 14, 21, 28, 35
3 1/2 = 3 7/14
2 6/7 = 2 12/14
<em>3 7/14 + 2 12/14 = 5 19/14</em>

∠P=∠R, ∠Q=2∠R
the three angles make a total of 180, so
∠P+∠R+∠Q=180
∠R+∠R+2∠R=180
∠R=45
∠P=45, ∠Q=90

Answer:
Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).
