Answer:
Theres no diagram or drop down menu
lmk when you get it and i will help you
Step-by-step explanation:
Let's solve for x using trigonometric relation ( Cos )
we know,

now



hence, the value of x is 
4x-y
x= 5
y= 6
replace in the ecuation above:
4•5-6= 20-6= 14
Answer:
100 degrees
Step-by-step explanation:
This is because AED And CED ARE supplimetary.
80+<CED=180
-80 -80
<Ced=100
Answer:
4.0731 cm
Step-by-step explanation:
Use pythagorean Theorem which is a^2 + b^2 = c^2 where a and b are the sides of the triangle and c is the hypotenuse, in other words the longest side.
Since x is in line with the center of the circle and is perpendicular with line that measures 15.6 cm we know that one side of the triangle is half of 15.6 or 7.8.
So then we input our known values into the formula and solve for the missing one. The formula looks like this
7.8^2 + b^2 = 8.8^2
solve for b and you get about 4.07431
