Answer:

H-L Theorem

Step-by-step explanation:

They tell you that they are right triangles, and you have your congruency marks. If they never had right angle indicators, this theorem would never work.

I hope this helps you out, and as always, I am joyous to assist anyone at any time.

Answer:

a) 16

b) 100

c) 64

d) $\frac{81}{4}$ [/tex]

Step-by-step explanation:

Perfect square trinomial:

A perfect square trinomial has the following format:

$(x \pm a)^2 = x^2 \pm 2ax + a^2$

x² – 8x

$x^2 - 8x = x^2 - 2ax$

So 2a = 8, a = 4. Then

$a^2 = 4^2 = 16$

The perfect square trinomial is $x^2 - 8x + 16$

b. x2 + 20x +

2a = 20, so a = 10

$a^2 = 10^2 = 100$

The perfect square trinomial is $x^2 + 20x + 100$

x² – 16x +

2a = -16, so a = -8.

$a^2 = (-8)^2 = 64$

The perfect square trinomial is $x^2 - 16x + 64$

d. x2 + 9x +

$2a = 9$ , so $a = \frac{9}{2}$

$a^2 = (\frac{9}{2})^2 = \frac{81}{4}$

The perfect square trinomial is $x^2 + 9x + \frac{81}{4}$ [/tex]

Answer:

1. 8.19, 2. 25.96, 3. 3.95

Step-by-step explanation:

use soh cah toa

1. cos is adjacent/hypotenuse

cos73=x/28

multiply both sides by 28

28cos73=x=8.186

2. sin is opposite over hypotenuse

sin68=x/28

multiply both sides by 28

28sin68=x=25.961

3. sin is opposite over hypotenuse

sin26=x/9

myltiply both sides by 9

9sin26=x=3.945
