Answer:

125

Step-by-step explanation:

Using the angle addition postulate,

<em>Parts</em><em> </em><em>of</em><em> </em><em>an</em><em> </em><em>Angle</em><em> </em><em>add</em><em> </em><em>up</em><em> </em><em>to</em><em> </em><em>form</em><em> </em><em>a</em><em> </em><em>new</em><em> </em><em>angle</em><em> </em><em>with</em><em> </em><em>the</em><em> </em><em>measure</em><em> </em><em>of</em><em> </em><em>that</em><em> </em><em>angle</em><em> </em><em>is</em><em> </em><em> </em><em>the</em><em> </em><em>sum</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>two</em><em> </em><em>separate</em><em> </em><em>angles</em><em>.</em>

<em>Add</em><em> </em><em>ABD</em><em> </em><em>and</em><em> </em><em> </em><em>DBC</em>

<em>65 + 60 = 125</em>

<em>ABC</em><em>=</em><em>1</em><em>2</em><em>5</em>

Faiza, Krish and Joe start cycling around the park from the same point at the same time. Faiza circles the park in 60 seconds, K
pishuonlain [190]

Answer:

The time at which they will all meet at a place together is 350 minutes

Step-by-step explanation:

The time it takes Faiza to cycle the park = 60 seconds

The time it takes Krish to cycle the park = 14 seconds

The time it takes Joe to cycle the park = 25 seconds

Therefore, the time they will all meet at a place together is given by their Lowest Common Multiple as follows;

LCM = 60 × 14 × 25 = 21,000 seconds

Therefore, the time at which they will all meet at a place together in minutes = 21000 seconds/(60)×minute/second = 350 minutes
