Answer:52
Step-by-step explanation:you just have to add the angles 66 and 62 which will give you 128 which you will subtract from 180 degrees which is the sum of all the angles in every triangle and you will get your answer 52
Since neither 5x nor -y has a "like term" in <span>2xy+xy, the sum of these quantities is simply
</span><span>2xy+xy + 5x - y = 3xy + 5x - y
You might want to write this as y(3x -1) + 5x. </span>
Answer:
Area shaded portion = 16/3 π - 8√3
Step-by-step explanation:
The shaded portion consists of 2 equal segment
∵ Two circles have the same radii = 4
∵ The the length of the common chord of the two circles = 4
∴ The central angle of each segment = π/3 (60° equilateral Δ)
∵ Area segment = area sector - area Δ
∵ Area sector = 1/2 r²Ф = 1/2 × (4)² × π/3 = 8/3 π
∵ Area Δ = 1/4 s² √3 = 1/4 × (4)² × √3 = 4√3
∴ Area segment = 8/3 π - 4√3
∴ Area shaded portion = 2(8/3 π - 4√3) = 16/3 π - 8√3

Answer:
8 x = 60.10251159
9 x = 3.66062978
Step-by-step explanation:
Hey There!
So to answer these questions we need to use the Law of sines
Consider the following image
So to find x in number 8 we setup an equation
now we solve for x
step 1 multiply each side by sin 90
now we have
if you plug the equation in a calculator you get that
x=60.10251159
<u>( make sure if it says to round to the nearest.... that you round before entering your answer)</u>
For number 9 the equation would be
now we solve for x
step 1 multiply each side by sin 24
now we have
if you plug this into a calculator you get that
x = 3.66062978
<u>(once again if it says to round to the nearest... make sure you round before you put in your answer.)</u>
