Answer:

yes

Step-by-step explanation:

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. Examples of isosceles triangles include the isosceles right triangle, the golden triangle, and the faces of bipyramids and certain Catalan solids.

GEOMETRY HELP!! WILL MARK BRAINLIEST IF RIGHT!!
Scrat [10]

Answer:

y = 13

z = 11

Step-by-step explanation:

14. We know that if the two triangles are congruent, then the hypotenuses will be the same. So we can say that

6y = 5y + 13

We can solve for y by subtracting 5 y from both sides and find out that y = 13.

15. Again, we know if the triangles are congruent then the two shorter legs will be the same, so we can say that:

3z = z + 22

2z = 22

z = 11

Elena-2011 [213]

Answer:

11/23 or 0.478

Step-by-step explanation:

1. Find the probability of selecting 2 red chips:

11/23 * 10/22 = 5/23

2. Find the probability of selecting 2 blue chips:

12/23 * 11/22 = 6/23

3. Add the two probabilities:

5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)

80% of x is 48 what is x and what is an equation that I can use to solve?<br><br> Please help!!
butalik [34]
X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!

attashe74 [19]

Answer:

Baxter drives at 57 kilometers per hour.

Step-by-step explanation:

In order to find the answer, you have to use the following formula to calculate the speed:

speed=distance/time

distance=399 km

time=7 hours

Now, you have to replace the values in the formula:

speed=399 km/7 hours

speed=57 km/hour

According to this, the answer is that Baxter drives at 57 kilometers per hour.
