Answer:

x = -4

Step-by-step explanation:

Step 1: Write equation

-x + 3 = 7

Step 2: Solve for <em>x</em>

Subtract 3 on both sides: -x = 4
Divide both sides by -1: x = -4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-(-4) + 3 = 7

4 + 3 = 7

7 = 7

What else would need to be congruent to show that triangle ABC and triangle XYZ is congruent by AAS

julia-pushkina [17]

Answer:

C. ∠B ≅ ∠Y

Step-by-step explanation:

This is because AAS means 2 angles and 1 side are congruent.

Which means there are two possible answers: B or C. But answer B says angle C and Z are congruent which would make both triangles congruent by ASA and not AAS

I don't understand..please help:

andrew-mc [135]

X is Andrews age and if x stands for Andrew then

x-28=5x-160

then you would do =+160 to both sides getting x+132=5x

subtract the x from the side with 132 and then do 4 divided by 132
getting 33
Andrew is 33

In the figure below, BCA ~ STR. Find cos C, sin C, and tan C. Round your answers to the nearest hundredth.

arsen [322]

Answer:

$\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63$

Step-by-step explanation:

According to the trigonometric ratios in aright triangle :

$\sin x =\dfrac{\text{Side opposite to x}}{\text{Hypotenuse}}\\\\\cos x =\dfrac{\text{Side adjacent to x}}{\text{Hypotenuse}}\\\\\tan x=\dfrac{\sin x}{\cos x}$

Given: ΔBCA ~ ΔSTR

Since , corresponding angles of two similar triangles are equal.

So, ∠C = ∠T ...(i) [Middle letter]

In triangle STR

$\sin T=\dfrac{\text{Side opposite to T}}{\text{Hypotenuse}}\\\\=\dfrac{26.4}{30.9}\approx0.85\\\\\cos x =\dfrac{\text{Side adjacent to T}}{\text{Hypotenuse}}\\\\=\dfrac{16.2}{30.9}\approx0.52\\\\\tan T=\dfrac{\sin T}{\cos T}\\\\=\dfrac{0.85}{0.52}\approx1.63$ ...(ii)

From (i) and (ii), we have

$\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63$
