If E is on the interior of ∠ABD, m∠ABE = (2x - 5)°, m∠EBD = (x + 1)°, and m∠ABD = 50°, find the value of x.

Answers

Answer 1
Answer:    
\displaystyle \n m\ \textless \ ABE + m\ \textless \ EBD = m\ \textless \ ABD \n \n (2x - 5)^o + (x + 1)^o = 50^o \n \n 2x-5+x+1=50 \n \n 3x - 4 = 50 \n \n 3x = 50+4 \n \n 3x = 54 \n \n x = (54)/(3) = \boxed{18^o}

Find a cofunction with the same value as the given expression. csc 52°A. sec 52°
B. sec 38°
C. sin 52°
D. sec 142°

Answers

To find a cofunction with the same value as the expression csc 52*, you would use the formula like this.  csc (x) = sec (90-x). So if you use csc(52) that equals sec(90-52). This in turn, equals sec(38). So the answer is B.

Find the probability distribution for the following function:P(x) =for x = 4, 6, and 8



P(3) = 2, P(5) = 3, P(7) = 4

P(3) = 9, P(5) = 10, P(7) = 11

P(3) = 1, P(5) = 2, P(7) = 3

P(4) = 3, P(6) = 4, P(8) = 5

Answers

Hello,
sorry, I haven't understood the question.

ANSWER D:
the probability must be defined for 4,6,8
P(4)=3
P(6)=4
P(8)=5
But probability must be <1

==> P(4)=3/12, P(6)=4/12 and  P(8)=5/12

So 3/12+4/12+5/12=12/12=1

Jessica rented a truck to move into another apartment. The rental charge is $140 per day plus $0.35 per mile. Write an equation to determine x, the number of miles she can drive the truck if the cost is y.

Answers

Answer:

y=0.35x+140

Step-by-step explanation:

Step one:

given data

The rental charge is $140 per day

additional charges per mile driven = $0.35 per mile

Step two:

Required

The expression for the total charges

let the number of miles be x, and the total charges be y

the expression for the total charges is

y=0.35x+140
