What is qr ? enter your answer in the box. units the figure shows what appears to be obtuse triangle q r s with obtuse angle r. point t is on side q r. single tick marks pass through segments q t and t r. point u is on side r s. double tick marks pass through segments r u and u s. point v is on side s q. triple tick marks pass through segments s v and v q. segment t v is drawn and has length 5.4. segment u v is drawn and has length 6.

The value of QR is 12.

Explanation:

It is given that the Points T,U, V are midpoints of the sides of ΔQRS . TV =5.4 and UV = 6.

The midpoint theorem states that the if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.

Since U and V are midpoints of RS and SQ respectively.

So by midpoint theorem length of QR is twice of UV.

Therefore, the length of QR is 32.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
