In a triangle, two angles have measures of 45º and 85º. What is the measure of the third angle in this triangle?

1 answer:

7 0

To figure out one measure of a triangle, we use A2+B2=C2
(Where a is the first measure times itself, b is the second side times itself and c is the longest side times itself). Once you figure that out and plug all your numbers into the formula, you can solve like a regular equation. 45 times 45 is 2,025. 85 times 85 is 7,225. We don't know c so we just put that as C2. Our equation- 2,025+7,225= C2
Add the numbers to get 9,250= C2
Our answer is 96. (Because 96 times itself is 9,250). The answer is not exact so I just rounded it to the nearest whole number.

<h3>What is odds against?</h3>

In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,

$\text{odd against}=\dfrac{P(\overline A)}{P(A)}$

Here, $P(\overline A)$ is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.

A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,

$P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}$

The probability of not winning is,

$P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}$

Thus, the odd against the winning is,

$\text{odd against}=\dfrac{\dfrac{4}{5}}{\dfrac{1}{4}}\\\text{odd against}=\dfrac{16}{5}\\\text{odd against}=3.2$

Thus, the odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.
