Given ∠C ≈ ∠B and ∠BDA is a right angle, are the two triangles, ΔBDA and ΔCDA congruent? If so, by what criterion?

2 answers:

5 0

Since angle B and angle C are congruent, angle BDA is a right angle, and the sides of angle B and C have to be congruent, since the angles are congruent, Triangle BDA and Triangle CDA are both congruent, by the Angle-Angle-Side Theorem, which is the criterion that fits this answer.

What is the median and mode

viktelen [127]

Median is the middle number

60, 60, 65, 70, 70, 85, 90

70 is your median

mode is the number(s) that show up the most
60 and 70 is your mode, since they show up twice (one more than the others)

Range is largest number minus the smallest
90 - 60 = 30, 30 is your range

Mean is all the numbers added together divided by the number of numbers there are
60 + 90 + 65 + 70 + 70 + 85 + 60 = 500
500/7 = 71.42
Mean = 71.42

hope this helps

Answer:

A. 3x^2 + 4 = 52

3x^2 = 52 - 4

3x^2 = 48

x^2 = 48/3

x^2 = 16

x = $\sqrt{16}$

x = 4

B. x^2 - 121 = 0

x^2 = 121

x = $\sqrt{121}$

x = 11

C. (b + 4 )2 = 49

2b + 8 = 49

2b = 49 - 8

2b = 41

b = 41/2

estamos construyendo una carretera que enlace los puntos a = 12 ,21 y b =(17,23) otro punto se encuentra en c =(3,9) es posible

Nadusha1986 [10]

Answer:

is not possible

Step-by-step explanation:

The question in English is

we are building a road that links the points a = (12 ,21) and b =(17,23) another point is in c =(3,9) it is possible that a single road allows to join these three points?

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$
