Find the angles a,b,c and d

maria [59]

Answer:

a°=79°[alternate angles]

c°=83°[alternate angle]

a° +d°=180°[straight angle]

79°+d°=180

or,d°=180-79

so,d°=101°

Now,

b°+c°=170°[sum of straight angle]

b°+83°=180°

b°=180°-83°

so,b°=97°

An experiment consists of rolling a die, flipping a coin, and spinning a spinner divided into 7 equal regions. The number of ele

oee [108]

Answer:

Option A.

<em>The number of elements in the sample space of this experiment is 84</em>

Step-by-step explanation:

The sample space for an experiment represents the number of possible results that may occur when conducting the experiment.

When throwing a die and observe the number obtained there are 6 possible results

When throwing a coin there are 2 possible results.

When spinning a wheel divided into 7 regions we have 7 possible outcomes.

If we combine these three experiments, then the sample space S is composed of the product of the possible results of each experiment.

$S = (6)(2)(7)\\\\S =84$
