Answer: Yes ΔRWS≈ΔQWT.

Step-by-step explanation:

We know that when two chords intersect each other inside a circle, the products of their segments are equal.

Therefore, QW\times WS=TW\times RW\\\Rightarrow\frac{QW}{RW}=\frac{TW}{WS}

Now in triangle QWT and triangle RWS

∠QWT=∠RWS     [Vertically opposite angles]

\frac{QW}{RW}=\frac{TW}{WS}

Therefore, By SAS similarity rule

ΔRWS≈ΔQWT

Therefore, yes ΔRWS≈ΔQWT.

We need help finding the means of the sides of this figure.<br> (Photo attached)<br><br> Thank you

Answer:

3) 5

4) 8.2

5) 6.8

6)FG = 6.4

7) EF = 3.6

8)DF = 4.8

Step-by-step explanation:

From the attached triangle, using trigonometric ratio we can find ∠G as; tan^(-1) (6/8)

Thus, ∠G = 36.87°

Still using trigonometric ratios;

FG/8 = cos 36.87°

FG = 8 cos 36.87°

FG = 6.4

3) EF + FG = EG

Since EG is 10, mean of EF and FG = 10/2 = 5

4) mean of EG and FG = (10 + 6.4)/2 = 8.2

5) EF + FG = EG

Thus; EF = EG - FG

EF = 10 - 6.4

EF = 3.6

Mean of EG and EF = (10 + 3.6)/2 = 6.8

6) FG = 6.4

7) EF = 3.6

8) Using trigonometric ratio;

DF/8 = sin 36.87

DF = 8 × 0.6

DF = 4.8

Solve for the ? angle
daser333 [38]

Answer:

50

Step-by-step explanation:

since all angles add up to 180

and since this is a right triangle the square in the corner is 90 degrees

so 40+90+x=180

130+x=180

subtract 130 from both sides

130-130+x=180-130

x=50

Hope that helps :)

What is z if -1/3+2z=-5/6?
Wittaler [7]
-1/3+2z=-5/6
-2/6+2z=-5/6
Add 2/6 to both sides:
2z=-3/6
2z=-1/2
Divide both sides by 2
z=-1/4

Hope this helps :)

If a solid has faces that consist of 2 equilateral triangles and 3 congruent rectangles, what type of solid is it?
svlad2 [7]
A right triangular prism is a solid that has faces that consist of 2 equilateral triangles and 3 congruent rectangles. It is also described to have two parallel faces and 3 other faces that belong to the same place (and are not parallel to the parallel pair of faces).
