Answer: AB = 6

Step-by-step explanation:

If CD = 12 , AC also = 12

B is the midpoint of AC so one side = 6

AB is one side of AC , so AB = 6

If two right triangles each have a 30° angle, then the
Scorpion4ik [409]

Answer:

b. Similar

Step-by-step explanation:

Although angles are congruent the triangles are not as sides need to be the same too.  Both shapes have 90 degree and 30 degree and add up to 180 degree in each triangle. Therefore each shapes angles are congruent but we dont know there size or scale, so they are similar. if they are the same (shape and size)- in other words, if the lengths of the sides and the angles are the same. So they are similar.

Because the angles are congruent and sizes are not shown they must be similar.

They cannot be obtuse as no angle is larger than 90 degrees and to be obtuse it would have to be larger than 90 deg and lower than 180 deg.

They cannot be equilateral as that means it couldn't be 30 degree and a right angle as equilateral means same angle sizes within 'one' triangle or for every or each triangle; as we know all triangles that are equilateral are 60, 60, 60 degrees to add up to 180 degree and cannot be an equilateral for this reason too as we have right angle triangles and equilateral are not right angles due to being 60 degree angle measures.

They are not fully congruent as we do not know there side measures so they have to be similar.

One endpoint of a segment is (12, −8). the midpoint is (3, 18). find the coordinates of the other endpoint.

Korvikt [17]
The answer is x = 10/3. You just have to add 21 to both sides of this equation then simplify. Hope this helped!

Answer plz if you put a not so nice or relevent answer i will do the same
gladu [14]

Answer:

1. A 2.D

Step-by-step explanation:

G is the number of girls who attended so that will be our product.

Since 75% of the girls attended the dinner and there are 12 girls on the team we are trying to find a part of the team that attended the dinner so

we would multiply a decimal times the whole.

Convert 75% into a decimal

\frac{75}{100}  = 0.75

Multiply that by 12 to equal G

0.75(12) = g

So the answer is A

Kim pick 2 1/3 lbs every 1/4 hour. We are asked how many she pick every hour.

Let set up a fraction to make the equation equivalent

\frac{2 \frac{1}{3} }{ \frac{1}{4} }  =  \frac{x}{1}

1/4 goes into 1 4 times. so we would multiply 4 by 2 1/3 to find the x value.

2\frac{1}{3}  \times 4

2 \frac{1}{3}  \times  \frac{12}{3}

\frac{7}{3}  \times  \frac{12}{3}

\frac{84}{9}

9 \frac{3}{9}

9\frac{1}{3}

so the answer is D
