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.

How many ounces of a 15% alcohol solution must be mixed with 8 ounces of a 20% alcohol solution to make a 17% alcohol solution?
Tasya [4]

Step-by-step explanation:

x = ounces of 20% solution

15% = 0.15

20% = 0.2

17% = 0.17

x × 0.15 + 8×0.2 = (8 + x)×0.17

x×0.15 + 8×0.2 = 8×0.17 + x×0.17

8×0.2 = 8×0.17 + x×0.02

8×0.03 = x×0.02

x = 8×0.03/0.02 = 12 ounces

we need to mix the 8 ounces of 20% with 12 ounces of 15% to get 17% alcohol (8 + 12 = 20 ounces of it).

Write the equation of the line parallel to the y axis at a distance of 7 units form it to is left​
Finger [1]

Answer:

x = -7

Step-by-step explanation:

Two parallel lines are lines that never intersect each other.

The y-axis can be written as x = 0.

Then if we want a parallel line to this one, it must be something like x = b

such that b ≠ 0.

Now we want that the distance between our line and the line x = 0 is 7 units to the left

(remember that the left is the negatie side of the axis)

then we can write:

b - 0 = -7

b = -7

The parallel line is x = -7
