The hypotenuse of a right triangle is 50 and the short leg is 30, find the projection of the leg onto the hypotenuse

gladu [14]

Consider the attached figure. All the triangles shown are similar, so

CB/CA = CD/CB
30/50 = projection/30
projection = 30^2/50
projection = 18

What is the midpoint of the line segment

Karo-lina-s [1.5K]

Answer:

The answer to your question is (-1, -1)

Step-by-step explanation:

Data

A (1, -6)

B (-3, 4)

Formula

Xm = $\frac{x1 + x2}{2}$

Ym = $\frac{y1 + y2}{2}$

Process

1.- Substitute the values in the formula

x1 = 1 x2 = -3

Xm = $\frac{1 - 3}{2} = \frac{-2}{2} = -1$

y1 = -6 y2 = 4

Ym = $\frac{-6 + 4}{2} = \frac{-2}{2} = -1$

2.- The midpoint is (-1, -1)

4. IF AABD ACBE, find the value of x. 27 cm 12 cm SE E 23.4 cm

snow_tiger [21]

Answer:

$x = 10.4$

Step-by-step explanation:

Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:

$\frac{BD}{BE} = \frac{AD}{CE}$

BD = 12 cm

BE = x

AD = 27 cm

CE = 23.4 cm

Plug in the values

$\frac{12}{x} = \frac{27}{23.4}$

Cross multiply

$x \times 27 = 23.4 \times 12$

$27x = 280.8$

Divide both sides by 27

$x = 10.4$
