Answer:

y=15

Step-by-step explanation:

Because of the exterior angle theorem angle A plus angle b or equal to 146.

so you set 5y+3+4y+8=146 and solve

5y+3+4y+8=146

9y+11=146

9y=135

y=15

<h3><u>Answer:</u></h3>

Option C is correct.

<h3><u>Step-by-step explanation:</u></h3>

5y + 3 + 4y + 8 + (180 - 146) = 180
=> 9y + 11 + 34 = 180
=> 9y + 45 = 180
=> 9y = 180 - 45
=> 9y = 135
=> y = 135 ÷ 9
=> y = 15

<h3><u>Conclusion:</u></h3>

Hence, Option C is correct.

Hoped this helped.

Square A B C D is shown. Each side is 30 yards long. A diagonal is drawn from point D to point B to form 2 triangles.

Viktor [21]

Answer:

Length = 30√2 yards.

Step-by-step explanation:

There is a plot of land of square shape that has 30 yards on each side. Jules owns this plot. He plans to divide the land in half by building a fence along the diagonal of the plot.

We have to calculate the length of the fence.

Now, the length of the diagonal will be the length of the fence.

So, the length = $\sqrt{30^{2} + 30^{2}} = 30\sqrt{2}$ yards. (Answer)

Given that f(x) = 2x + 1 and g(x) = −5x + 2, solve for f(g(x)) when x = 3.

ANTONII [103]

$f(x)=2x+1 \\
g(x)=-5x+2 \\ \\
f(g(x))=2(-5x+2)+1=-10x+4+1=-10x+5 \\
f(g(3))=-10 \times 3+5=-30+5=-25 \\
\boxed{f(g(3))=-25}$

The answer is C.
