Answer:

2. ΔABC is isosceles

Step-by-step explanation:

Given : m∠A = 50

m∠BCD = 180 - (m∠BDC + m∠DBC)

              = 180 - (100 + 30)

              = 50

then

m∠A = m∠BCD

therefore ΔABC is isosceles

Write an equation of the line that is perpendicular to the line y =
pogonyaev

Answer:

c) y= -3x + 3

Step-by-step explanation:

Given equation

y= 1/3x+6

Here slope m1 = 1/3

We know that the slope of perpendicular lines

m1*m2 = -1

slope of perpendicular line m2 = -1/m1

                                                    = -1/ (1/3)

                                              m2 =  -3

Also the line passes through (2, -3)

equation of line is given by y = mx+b

y= -3

x=  2

m2 = -3

Applying above values to the equation of line,

-3 = (-3*2)+b

b=3

Hence equation of perpendicular line is y = -3x + 3

When two probabilities
Ivenika [448]

Answer: True  

Step-by-step explanation: Because if we have two independent events and want to know the probability of their happening at the same time, we multiply the two probabilities together.  "Two events happening at the same time" is a compound event.  We more often see this as "P(xy)," the probability of x AND y.

BabaBlast [244]

Answer:

x=10

Step-by-step explanation:

x^2 - 10 - (9x) = 0

x^2 - 9x - 10 = 0

(x - 10) + (x + 1) = 0

x= 10

x = -1
