Answer:

a

Step-by-step explanation:

We are given that

D is the mid-point of AB and E is the mid-point of AC.

We have to find the missing information in given proof of DE is equal to half of BC.

Proof:

D is the mid-point of AB and E is the mid-point of AC.

The coordinates of A are (2b,2c)

The coordinates of D are (b,c)

The coordinates of E are (a+b,c)

The coordinates of  B are (0,0)

The coordinates of  C are (2a,0)

Distance formula:\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using the formula

Length of BC=\sqrt{(2a)^2+(0-0)^2}=2a units

Length of DE=\sqrt{(a+b-b)^2+(c-c)^2}=a units

BC=2a=2\times DE

DE=\frac{1}{2}BC

Hence, proved.

Option A is true.

lions [1.4K]

Answer:

x=5

Step-by-step explanation:

According to SSS, RPS and RPQ should be similar angles. Since the length RP is the same, then RQP and RSP should be similar too. Therefore PRS and PRQ should be similar too. Since QP and RS are the same (7) then QR and PS needs to be same in length too.

2x+3 = 4x-7

10 = 2x

x=5

mestny [16]

Answer:

C

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanC = \frac{opposite}{adjacent} = \frac{AB}{BC} = \frac{c}{a} , then

C = tan^{-1} (\frac{c}{a} )
