In the figure, angle ABC and angle ADB are each right angles. Additionally, AC = 17.8 units and AD = 5 units. What is the length

Marizza181 [45]

Answer:

DB = 8

Step-by-step explanation:

Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is

$\frac{DB}{DC}$ = $\frac{AD}{BD}$ , substitute values

$\frac{DB}{17.8-5}$ = $\frac{5}{BD}$

$\frac{DB}{12.8}$ = $\frac{5}{BD}$ ( cross- multiply )

DB² = 64 ( take the square root of both sides )

DB = $\sqrt{64}$ = 8

use the point-slope equation to identify the slope and the coordinates of a point on the line y – 4 = 1/2 (x – 1). the slope of

mihalych1998 [28]

Answer:

The slope of the line is $\dfrac{1}{2}$ and a point on the line is $(1, 4)$

Step-by-step explanation:

The general point slope of line passing through $(x_1,y_1)$ and having slope as m.

$y-y_1=m(x-x_1)$

The given equation of the straight line,

$y-4=\dfrac{1}{2}(x-1)$

Comparing this to the general equation we get the point as $(1, 4)$ and slope as $\dfrac{1}{2}$

Which of the following statements must be true, given that AABC= AXYZ

Leno4ka [110]

Answer:

B. m ∠Z = 32°

Step-by-step explanation:

Given:

Δ ABC ≅ Δ XYZ

m ∠ C = 32°

When 2 triangles are congruent we can say that all side of 1 triangle are equal to corresponding sides of other triangle.

Side AB= Side XY And Side BC = Side YZ and side AC = side XZ

Also,

When 2 triangles are congruent we can say measure of all angles of 1 triangle are equal to measures corresponding angles of other triangle.

m ∠A = m ∠X and m ∠B = m∠Y and m ∠C = m ∠Z

m ∠ C = 32° hence m ∠ Z = 32°
