The formula for calculating the total interior angle in a
regular polygon is given as:
total interior angle = (n -2) 180
where n is the number of sides and since there are sides:
total interior angle = 360°
To get this angle, we know that it is the summation of all
angles:
360° = angle A + angle C + angle B + angle D ---> 1
Looking closely, we can see that segments BC and AD are
parallel which means that:
angle A + angle C = angle B + angle D ---> 2
Substituting equation 2 to 1:
360 = 2 (angle A + angle C)
angle A + angle C = 180
(x + 16) + (6x – 4) = 180
Answer:
B
Step-by-step explanation:
Tracie’s bus travels towards her home at an average speed of StartFraction one-half EndFraction mile per minute.
To find the specification limit such that only 0.5% of the bulbs will not exceed this limit we proceed as follows;
From the z-table, a z-score of -2.57 cuts off 0.005 in the left tail; given the formula for z-score
(x-μ)/σ
we shall have:
(x-5000)/50=-2.57
solving for x we get:
x-5000=-128.5
x=-128.5+5000
x=4871.50
<h3>There are 96 roses altogether</h3>
<em><u>Solution:</u></em>
Let "x" be the number of roses
From given,
<em><u>1/4 of the roses are red</u></em>
<em><u>1/3 of the remainder are yellow</u></em>
Therefore,
<em><u>Rest are pink</u></em>
Therefore,
There are 24 more pink roses than red roses
Therefore,
Number of pink roses = 24 + red roses
Thus there are 96 roses altogether
