Answer: 49 cm^2

Step-by-step explanation:

The length of the small pink square box will be:

L^2 = 9

L = sqrt( 9 )

L = 3

The length of the big pink square box will be:

L^2 = 16

L = sqrt( 16 )

L = 4

The length of the yellow square box will be:

4 + 3 = 7

The area of the third square box will be

A = 7^2

A = 49 cm^2

Which of the following is a result of the construction of a median of a triangle?

antoniya [11.8K]

Answer:

1)An angle of the triangle is bisected.

ONLY IN ISOSCELES AND EQUILATERAL TRIANGLE.

2) A perpendicular segment is created from a vertex to the opposite side.

True

3)A side of the triangle is bisected. TRUE

4) The center of the triangle is found. TRUE

The point where three medians meet inside the triangle, that point is the centroid of the triangle.

Step-by-step explanation:

Median of a triangle is defined as the perpendicular line drawn from one vertex of a triangle to the opposite side.

It divides the side of the triangle into two EQUAL PARTS.

If the given triangle is an isosceles or an equilateral triangle, median is also an ANGLE BISECTOR

The given statements implies

1)An angle of the triangle is bisected.

ONLY IN ISOSCELES AND EQUILATERAL TRIANGLE.

2) A perpendicular segment is created from a vertex to the opposite side.

True

3)A side of the triangle is bisected. TRUE

4) The center of the triangle is found. TRUE

I dont understand please help

DiKsa [7]

$2 \frac{1}{2}+(-2\frac{1}{4})$

This is equal to:

$2\frac{1}{2}-2\frac{1}{4}$

When you add a negative number, it turns into subtraction.

First, I would change it to mixed numbers:

$\frac{5}{2}-\frac{9}{4}$

Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:

$\frac{10}{4}-\frac{9}{4}$

Now, you simply subtract:

10-9=1

1/4 is your answer.

I hope this helps :)
