In the figure, ∠4 is an exterior angle to ∠AUL.

marin [14]

a) Here, sum of two non-adjacent angles: 52 + 25 = 77

Now, ∠3 = 180 - 77 [ sum of all angles in a triangle is 180 ]

so, ∠3 = 103

Now, ∠3 + ∠4 = 180 [ Supplementary angles ]

So, ∠4 = 180 - ∠3

∠4 = 180 - 103 = 77

∠4 = 77 [ which is sum of two non-adjacent angles ]

....Hence proved.

b) m∠4 = 77

[ Solved in previous section ]

Hope this helps!

RCX)=2VX SCx) = x(RSX4=

aev [14]

Given the two functions:

$\begin{gathered} R(x)=2\sqrt[]{x} \\ S(x)=\sqrt[]{x} \end{gathered}$

We need to find (RoS)(4). THis is the functional composition. We take S(x) and put it into R(x) and then put "4" into that composed function. Shown below is the process:

$(RoS)(x)=2\sqrt[]{\sqrt[]{x}}$

When we plug in "4", into "x", we have:

$\begin{gathered} (RoS)(x)=2\sqrt[]{\sqrt[]{x}} \\ (RoS)(4)=2\sqrt[]{\sqrt[]{4}} \\ =2\sqrt[]{2} \end{gathered}$

What is wrong with this “proof”? “Theorem” For every positive integer n, if x and y are positive integers with max(x, y) = n, th

VMariaS [17]

The assumption of the inductive step is not correct. If $\mathrm{max}(x,y)=2$ , for instance, it's entirely possible that $x=1$ and $y=2$ .

Solve the system by substitution.<br> y = -9x<br> y = 2x + 33

Gwar [14]

Answer:

$y = - 9x \\ theny = 2x + 33 \\ - 9x = 2x + 33 \\ - 9x - 2x = 33 \\ - 11x = 33 \\ x = \frac{ - 33}{11} = - 3 \\ x = - 3 \\then\\ y=-9×-3=21\\ thank \: you$
