PLEASE HELP ASAP JUST CLASSIFY THE TRIANGLE NOTHING ELSE
1 answer:
Given:
The figure of a triangle.
To find:
The category of the triangle.
Solution:
In the given triangle two angles are equal and their measure is 78 degrees. So, the measure of third angle is
(Angle sum property)
In the given triangle only two angles are equal in means their opposite sides are also equal.
We know that base angles of an isosceles triangle are equal. So, the triangle is isosceles.
All angles are less than 90 degree. So, the triangle is acute.
Therefore, the given triangle is an isosceles acute triangle and the correct option is B.

Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. Find the standardized score (z-score), relative to all U.S. births, for a baby with a birth length of 45 cm.
Here, we use . So
b. Find the standardized score of a birth length of 45 cm. for babies born one month early, using 47.4 as the mean.
Here, we use . So
c. For which group is a birth length of 45 cm more common?
For each group, the probability is 1 subtracted by the pvalue of Z.
Z = -2.88 has a lower pvalue than Z = -0.96, so for Z = -2.88 the probability 1 - pvalue of Z will be greater. This means that for 40 weeks gestation babies a birth length of 45 cm is more common.
