Thanks for your question!
We know the third angle in the triangle is 65 because it is a linear pair. We also know that all the angles in a triangle adds up to 180. So:
4k + 5 + 6k + 10 = 180 - 65
10k + 15 = 115
10k = 100
k = 10
Hope this helped!
Answer:
y=y(.11y+8)
Step-by-step explanation:
Answer: 7.42x10^3 . . . . .
Answer:
167.5
Step-by-step explanation:
For surface area all you have to do is multiply each number by one of the other numbers x2.
Area of shaded part = area of circle - area of the square
= pi (6)^2 - area of the square.
Area of square = (m of one side) ^2
measure of of side is found as follows:-
6^2 = 2s^2 where m of the side = 2s
s = sqrt 18 so side of square = 2 sqrt18
area of square = (2 sqrt18)^2 = 4*18 = 72
area of shaded region = 36pi - 72 = 41.1 sq units to neraest tenth
