Which statement is not used to prove that ΔABC is similar to ΔADE? triangles ABC and ADE in which point E is between points A an

d C on segment AC and point D is between points A and B on segment AB, angle A is a right angle AC is a transversal line passing ED and CB. Angle A is congruent to itself, due to the reflexive property. Segments ED and CB are parallel. The sum of angles A and B are supplementary to angle C.

Answer:

The correct option is;

The sum of angles A and B are supplementary to angle C

Step-by-step explanation:

The statements are analysed as follows

1. Angle A is congruent to itself reflective property

Which shows that ΔABC and ΔADE have a common and equal angle

2. Segment ED and CB are parallel

From the transversal line passing EB and CB which shows that the angles ∠ADE and ∠ABC are equal and also ∠AED and ∠ACB are equal

The statement is used to prove similarity between the ΔABC and ΔADE

3. The sum of angles A and B are supplementary to angle C

The above statements relates to only ΔABC and i does not show similarity between ΔABC and ΔADE.

Readme [11.4K]

The probability that a single radar set will detect an enemy plane is 0.9. if we have five radar sets, what is the probability that exactly four sets will detect the plane?

Solution: The given random experiment follows binomial distribution with p=0.9,n=5

Let x be the number of radar sets that will detect the plane.

We have to find P(x=4)

P(x=4)=\binom{5}{4}0.9^{4}(1-0.9)^{5-4}      

               =5\times 0.6561 \times 0.1

               =0.3281

Therefore, the probability that exactly four sets will detect the plane is 0.3281

Rewrite the following equation in slope-intercept form. 17x + 15y = 5 Write your answer using integers, proper fractions, and im
omeli [17]
Answer:
y = \frac{-17}{15} x + \frac{1}{3}

Explanation:
The slope-intercept form of the equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
17x + 15y = 5

To put it in the slope-intercept formula, we should isolate the y as follows:
17x + 15y = 5
15y = -17x + 5
y = (-17/15) x + (5/15)
y = \frac{-17}{15} x + \frac{1}{3}
where:
m is the slope = -17/15
c is the y-intercept = 1/3

Hope this helps :)

I did bad but what's the answer for this?
Setler [38]

Answer:

28 degrees

Step-by-step explanation:

A triangle is always equal to 180 degrees so add the degrees together

40+2x+3x=180

40+5x=180

5x/5=140/5

x=28
