Answer:
Measure of angle R: Measure of angle S:
42 degrees <em><u>90 - 42 = 48</u></em>
30 degrees <em><u>90 - 60 = 30</u></em>
84 degrees <em> </em><em><u>90 - 84 = 6</u></em>
<em><u>Complimentary angles are angles whose sum is 90 degrees</u></em>
A possible perimeter for the rectangle would be 28
Area=L x W
40/10=4
Width=4, Length=10
Perimeter=L+L+W+W
4+4+10+10=28
Answer: y=-2/3x-2/3
Step-by-step explanation:
concept to know: two lines that are perpendicular has opposite reciprocal slopes.
y=-2/3x+b
in order to find b or the y-intercept, we need to plug in a point
3=-2/3(-4)+b
3=8/3+b
b=-2/3
y=-2/3x-2/3
Hope this helps!! :)
Answer:
The <em>required probability</em> is
.
Step-by-step explanation:
Let <em>A </em>be the event of rolling the number cube.
Let <em>B</em> be the event of tossing the coin.
Total number of possibilities of rolling the number cube and tossing the coin are <em>12 </em>here.

where <em>H</em> means Head on toss of coin and <em>T</em> means Tails on toss of coin.
Formula for probability of an event <em>E</em> is:

Here, we have to find the probability of event 'E' i.e. getting a 6 on number cube and heads on coin.
Number of favorable cases are <em>1 </em>and total cases are <em>12</em>.
