Which property of congruence whould prove BD ≡ BD?

The triangle ABD and CBD has the same side = BD
Because they get the same side, they applied to the rule "reflexive property".
If you look at ABD, CBD, they are reflecting each other like a mirror.

The answer is first option

Hey! Let me help you on this one.

First of all, let's examine these two triangles.

Yes, they are indeed congruent. For example, angle D is congruent to angle A.

In order for us to find measures of angle B, let's find the measure of its congruent angle - E

In order for us to find it, we need to know that if we add all the measures of angles, we will get 180. 

74+50+x=180

Now, let's solve this

x= 180-74-50

Simplify it.

X= 56

As we can see, E is set at 56 degrees, meaning that the angle congruent to it is also set at 56 degrees.

Answer: Measure of angle B is 56 degrees.

Find the missing side lengths. Leave your answers as radicals in simplest form.
sattari [20]

Answer:

see explanation

Step-by-step explanation:

To find x use the sine ratio in the right triangle and the exact value

sin60° = \frac{\sqrt{3} }{2} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{14\sqrt{3} }{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x \sqrt{3} = 28\sqrt{3} ( divide both sides by \sqrt{3} )

x = 28

-----------------------------------------------------------

To find y use the tangent ratio in the right triangle and the exact value

tan60° = \sqrt{3} , then

tan60° = \frac{opposite}{adjacent} = \frac{14\sqrt{3} }{y} = \sqrt{3} ( multiply both sides by y )

14\sqrt{3} = y \sqrt{3} ( divide both sides by \sqrt{3} )

y = 14
