Which angle has the same measurement as angle DEA, and how do you know that the measurement is the same? Will mark Brainly or how ever you call it.

Which Angle Has The Same Measurement As Angle DEA, And How Do You Know That The Measurement Is The Same?

Answers

Answer 1

Answer:

∠DEA=∠BAC

Step-by-step explanation:

∠DAE=∠BCA (corresponding angles)

Angles in a triangle add up to 180:

Angles in ΔDAE=Angles in ΔABC

∠DAE+∠EDA+∠DEA=∠BCA+∠ABC+∠BAC

∠EDA+∠DEA=∠ABC+∠BAC (since ∠DAE=∠BCA, we can cancel them out)

∠DEA=∠BAC (∠EDA=∠ABC=90)

Answer:

x=6

Step-by-step explanation:

x/15=8/20

Multiply both sides by 10:

x/15*10=8/20*10

Simplify:8/20*10

2x/3=4

Multiply both sides by 3:

3*2x/3=4*3

b) Use the total of the results to estimate the

probability of Ben of hitting the target.

Answers

Answer:

[tex]P(Hits) = 0.70[/tex]

Step-by-step explanation:

Given

[tex]Throws = 120[/tex]

[tex]Hits = 84[/tex]

[tex]Miss = 36[/tex]

See attachment for result

Required

Determine the probability of hitting the target

This calculated using:

[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]

[tex]P(Hits) = \frac{84}{120}[/tex]

[tex]P(Hits) = 0.70[/tex]

Hence, the probability of hitting the target is 0.70

Maya has 54 cubic feet in her garden she already has 4.5 cublc feet of soil .Soil bags have 1.5 how many bags should maya purchace.

Answers

Answer: 33

Step-by-step explanation:

The cubic feet needed is 54 and she already has 4.5 cubic feet of soil. This mean that she will need 49.5 more.

= 54 - 4.5

= 49.5

Since each soil bag has 1.5, the number of soil bags needed will be:

= 49.5 / 1.5.

= 33

Therefore, she'll need 33 bags

what is the solution set of this inequality x < -10 i need help

Answers

Answer:

x= 1 (any number greater than -10)

Step-by-step explanation:

">" this sign shows that any number greater than -10 can be x. There is no specific answer.

Answer:

The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.

Step-by-step explanation:

When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.
