Answer: D

Step-by-step explanation:

Remember that the Opposite side to an angle is in the same order of length as the Angle. So, 90 = 12, and  60 = 8. Using Cross multiplication, this answer can be solved:

\frac{90}{12} = \frac{60}{n}  , 60 x 12 = 720, and 90 x 8 = 720. N = 8.

\frac{90}{12} = \frac{30}{n} , 30 x 12 = 360, and 90 x 4 = 360. N = 4

You have a bag with 100 pennies. One of the 100 pennies is weighted so that it lands on heads 90% of the time. The rest of them
masha68 [24]

Answer:

0.160275

Step-by-step explanation:

P(5 time heads) =P(fair penny and 5 time heads + weighted penny and  5 time heads)

probability of fair penny = 99/100 (as one is removed)

probability of heads = 50% = 0.5 flipped 5 times

probability of weighted penny = 1/100

probability of heads for this penny = 90% = 0.9

substituting, we have

=(99/100) * (1/2)*5  +  (1/100) * (0.9)5  = 0.036842

hence from Bayes theorem

P(weighted penny | 5 time heads) =P(weighted penny and 5 time heads) / P(5 time heads)

=(1/100)*(0.9)5 /0.036842 =0.160275

How do you find the inequality for a triangle when it only gives you two sides
MArishka [77]

Triangle Inequality Theorem is used to find the inequality for a triangle when it only gives you two sides

<em><u>Solution:</u></em>

We can find the inequality for a triangle when it only gives you two sides by Triangle Inequality Theorem

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

This rule must be satisfied for all 3 conditions of the sides.

Consider a triangle ABC,

Let, AB, BC, AC be the length of sides of triangle, then we can say,

Acoording to Triangle Inequality Theorem,

sum of any 2 sides > third side

BC + AB > AC

AC + BC > AB

AB + AC > BC

For example,

When two sides, AB = 7 cm and BC = 6 cm is given

we have to find the third side AC = ?

Then by theorem,

Let AC be the third side

AB + BC > AC

7 + 6 > AC

Thus the inequality is found when only two sides are given
