Answer:
The measurement of x is 106° and the measurement of y is 74°.
Step-by-step explanation:
The definition of an isosceles trapezoid is a trapezoid that has two pairs of congruent base angles. One pair at the top and the other pair at the bottom.
When you look at the trapezoid, you are given an angle. This angle measures 74°. Since base angles are congruent in an isosceles trapezoid, then the measurement of y is also 74°.
Another thing about isosceles trapezoids and all trapezoids is that they all have an interior angles sum of 360°. Interior means all of the angles inside the shape. So, since we know the bottom base angles both have a measurement of 74°, then we can add these angles together.
74 + 74 = 148
Now, we subtract 148 from 360 so we can find the measurement of x.
360 - 148 = 212
Now since there are two top base angles, then we will divide 2 from 212.
212 ÷ 2 = 106
So, the measurement of x is 106°.
Answer:
cos
Step-by-step explanation:
take 31 degree as reference angle
using cos rule
cos 31=adjacent/hypotenuse
0.85=14/x
x=14/0.85
x=16.47
x=16.5
What are you solving for?
You take the area and find the square root
V V
16 √
so you would be looking for √16 which equals 4
then you would add 4 by the length of the other 4 side to find the perimeter, which is ironically 16
The equation is:

And
Total number of pages are 351
Step-by-step explanation:
The equation has to be formed by using the given information.
Let p be the total number of pages in the novel
Then
1/3rd of the p will pe:

Total pages read by John = 114
Then according to the statement

We can solve the equation to get the total pages of the novel

The equation is:

And
Total number of pages are 351
