ABCD is a quadilateral in which AD=BC and angle DAB=angle CBA prove that BD=AC

Mathematics
1 answer:
likoan [24]3 years ago
8 0

Step-by-step explanation:

Given data:

ABCD is a quadrilateral.

AD = BC – – – – (1)

∠DAB = ∠CBA – – – – (2)

<u>To prove that BD = AC:</u>

In ΔABD and ΔBAC,

AD = BC (given side)

∠DAB = ∠CBA (given angle)

AB = BA (reflexive side)

Therefore ΔABD ≅ ΔBAC by SAS congruence rule.

By corresponding parts of congruence triangles,

BD = AC

Hence proved.

Solution:

Given: 35.052

The standard form is: 35.052

3 is in the tens place. 3 = 3 × 1

5 is in the tens place. 5 = 5 × 1

0 is in the tenths place. 0.0 = 0 × 1/10

5 is in the tenths place. 0.05 = 5 × 1/100

The value k needed for the transformation of f(x) to g(x) = f(k · x) is equal to 3.056.

<h3>How to find the find the dilation factor</h3>

In this problem we have the following relationship bewteen the two <em>quadratic</em> equations: g(x) = f(k · x), which means that for all y the following relationship between f(x) and g(x):

k = \frac{x_{g}}{x_{f}}

Let suppose that y = 3, then x_{f} = - 5.5 and x_{g} = - 1.8, then the value k is:

k = (- 5.5)/(- 1.8)

k = 3.056

The value k needed for the transformation of f(x) to g(x) = f(k · x) is equal to 3.056.
