Answer:
48.5654 degrees to the nearest ten thousandth.
Step-by-step explanation:
We can use the cosine rule to do this
First find m < C:
45^2 = 34^3 + 34^2 - 2.34.34 cos C
Cos C = [45^2 - (34^3 + 34^2 )] / (-2312)
= -287 / -2312
= 0.1241349
m < C = 82.8692 degrees
Therefore m < B = 180 - 82.8692) / 2 (as ABC is an isosceles triangle).
= 48.5654 degrees
A conclusion which can be derived from these random samples is that: B. the students in grades 11 and 12 scored higher than the students in grades 9 and 10.
<h3>What is a median?</h3>
A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.
Based on the information provided for these samples, we can logically conclude that the students in grades 11 and 12 scored higher than the students in grades 9 and 10 because a median score of 86 is greater than a median score of 79.

Answer:
thats too much and thats tuff
Step-by-step explanation:
Answer:
3+4i
Step-by-step explanation:
let x be the answer
(3-4i)x=25
x=25/(3-4i)
multiply by the conjugate
x=(25(3+4i))/25
x=3+4i
I cannno t see that picture bud butttt hope this helps it is 643222 + ( . ) = 2
