AE= 30 because it's BD x2
densk [106]3 years ago

Answer:

The length of AE is 30 units.

Step-by-step explanation:

Given that B is the mid point of AC and D is the mid-point of CE in ΔABC.

Also, BD=15 units

we have to find the length of AE

By mid-point theorem

The line joining the mid-points of two sides of triangle is parallel to third side and also half of the length of third side.

∴ BD=\frac{1}{2}AE

15=\frac{1}{2}\times AE

AE=15\times 2=30 units

Hence, the length of AE is 30 units.

Scrat [10]

Answer:

a² + b²

Step-by-step explanation:

(a + b)² - 2ab ← expand parenthesis using FOIL

= a² + 2ab + b² - 2ab ← collect like terms

= a² + b²

Megan constructed triangle ABC. In Megan's triangle,
mylen [45]

Answer:

21°, 84°, 75° are the angles

Step-by-step explanation:

Total angle in a triangle is 180.

x + 4x + (5x - 30) = 180

10x - 30 = 180

10x = 210

x = 21°

Angles are:

A: 21°

B: 4(21) = 84°

C: 5(21) - 30 = 75°

My equation equals 180. With the 3 variables missing
Natasha_Volkova [10]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, and it needs additional information before it can be answered.

However, a possible question could be that we generate an equation that has 3 variables and equals 180.

A possible question is:

<em>The sum of three consecutive numbers is 180. What is the highest number?</em>

<em />

<em>And the solution is as follows:</em>

Let the three numbers (in order of smallest to greatest) be x, y and z

So, the sum is:

x + y + z = 180

Since the numbers are consecutive, then the following relationship exist:

y = x + 1

x = x + 2

Substitute x + 1 for y and x + 2 for z in x + y + z = 180

x + x + 1 + x + 2 = 180

Collect Like Terms

x + x + x = 180 - 3

3x = 177

Solve for x

x = 177/3

x = 59

The value of the highest being is:

z = x + 2

z = 59 + 2

z = 61

<em>You can generate as many equation as possible</em>
