Answer:

d=1

Step-by-step explanation:

Move 7 to the other side by subtracting 7 on both sides:

2d+7-7=9-7

The equation now looks like this:

2d=2

Divide 2 on both sides:

2d/2=2/2

The equation now looks like this:

d=1 which is the answer

Please help!!! ABCD is a square with diagonals intersecting at E. What is the length of BE
Snezhnost [94]

Answer:

BE = 4\sqrt2

Step-by-step explanation:

Given

The attached square

Required

Find BE

First, we calculate BD (the diagonal) using Pythagoras theorem.

BD^2 = BA^2 + AD^2

Since the shape is a square, then

BA = AD = 8

So:

BD^2 = 8^2 + 8^2

BD^2 = 2(8^2)

Take square roots

BD = \sqrt{2(8^2)

BD = \sqrt{2} * 8

BD = 8\sqrt{2}

BE is half BD.

So:

BE = \frac{1}{2} * BD

BE = \frac{1}{2} * 8\sqrt2

BE = 4\sqrt2

Which of the following statements are enough to prove that triangles EFI and GFH are similar?
SCORPION-xisa [38]

To Prove: ΔEFI ~ Δ GFH

Proof:

When two triangles are similar, their corresponding sides are Proportional and their corresponding interior angles are equal.

Two Triangles can be proven similar by following Similarity Criterion.

1. AA

2.SSS

3.SAS

→∠EFI=∠GFH-------[Vertically Opposite angles]

The Other statement which is needed to prove that triangles EFI and GFH are similar is

 Option C:→  ∠E ≅ ∠G

So, Two triangles ΔEFI and Δ GFH are Similar by Angle-Angle(AA) Criterion.
