Find the values of x and y.

Mathematics
1 answer:

Answer:

x=90 y=43

Step-by-step explanation:

by looking at the diagram you can infer that the triangles are similar, this means that angle B and angle C both equal 47 degrees. you can also infer by the straight angle underneath both angles the both angle Ds add up to 180 and because they are similar triangles that means they are right angles giving you the x value, 90 degrees. after this you know that a triangle adds up to equal 180 degrees meaning if you add 90 and 47 together and subtract that from 180 you get the value of y, 43.

Work out the unknown angles. Give reasons for each answer.
zalisa [80]
A)

Because the sum of angles in a triangle must equal 180° we can say:

62+α+90=180

α+152=180

α=28°

b)

Since all sides have equal length, all angles must have equal measure.  (This is an equilateral triangle).  And again, because the sum of the angle must be 180° we can say:

b+b+b=180

3b=180

b=60°

In the equation below, what is the value of b? 4(x-2)^2-7=ax^2+bx+c
Finger [1]
We have 4(x^2 - 2x + 4) - 7 = 4x^2 - 8x + 16 - 7 = 4x^2 - 8x + 9;
So, 4x^2 - 8x + 9 = <span>ax^2+bx+c ;
The value of b is -8.</span>

Answer:

C

Step-by-step explanation:

Normal distribution has a unique characteristic of having equal mean and median values. If mean was higher than median, then the distribution would be positively skewed. Mean lower than median would appear in distributions negatively skewed. Each data set has a median value.
