WHAT IS THE MEASURE OF ANGLE A

madreJ [45]

Answer:

∠A = 100

∠B = 50

∠C = 30

Step-by-step explanation:

Sum of all angles of triangle = 180

∠A + ∠B + ∠C = 180

2x +x + x - 20 = 180 {Combine like terms}

4x - 20 = 180

Add 20 to both sides

4x = 180 + 20

4x = 200

Divide both sides by 4

x = 200/4

x = 50

∠A = 2x = 2*50 = 100

∠B = x = 50

∠C = x - 20 = 50 - 20 = 30

At a certain non-profit organization, 51% of employees are college graduates and 47% of employees have more than ten years of ex

Lady bird [3.3K]

Answer: 0.21

Step-by-step explanation:

Let A denotes the event that employees are college graduates.

B denotes that the event that employees have more than ten years of experience.

As per given , we have

P(A)=0.51

P(B)=0.47

P(A∪B)=0.77

We know that , $P(A\cup B)=P(A)+P(B)-P(A\cap B)$

$0.77=0.51+0.47-P(A\cap B)$

$P(A\cap B)=0.51+0.47-0.77=0.21$

Hence, the probability that a randomly selected employee will have more than ten years of experience and be a college graduate = 0.21

How do I find the missing side lengths?

KIM [24]

Use sin(45)= 5sqrt2/x
Then you would multiply x to sin(45) then divide sin(45) by 5sqrt2
and you would get
10 for M
You would then use Pythagorean theorem and get
3sqrt 10

Hope this helps.. BRAINLIEST
