Answer:
x = 10, y = 20
Step-by-step explanation:
Form a system of equations:
From the picture at the bottom you can see that vertical angles are equal, so:
Then, since the angles all together will add up to 360, you can do
subtract 70 from both sides
With the equation 3x + 2y = 70, multiply both sides by 2
Subtract the two equations:
Plug this into one of the original equations

Answer: hello your question is incomplete attached below is the complete question
answer :
a) ( option D )
b) A = 1/2 (6)(3) ( option B )
c) Area of shaded region = 9
Step-by-step explanation:
<u>a) Using integration with respect to x </u>
Area = ( note a = 10 )
= y^2/2 - 4y |⁷₄ + 10y - y^2/2 |¹⁰₇
= 33/2 - 12 + 30 - 51/2 = 9
hence the best integral from the options attached is option D
= [ 10x - x^2 /2 - x^2/2 - 9x ] ³₀
= 30 - 9/2 - 9/2 - 12 = 9
<u>b) Using Geometry </u>
Area = 1/2 * base * height
= 1/2 * 6 * 3
= 9
the first one is the answer to #1
and the second one is the answer to #2
