∠1 ​ and ∠2 are supplementary. ∠1=124°∠2=(2x+4)° Select from the drop down menu to correctly answer the question.
Alex_Xolod [135]
Remark
Supplementary angles add up to 180o. 

Givens
<1 = 124
<2 = 2x + 4

I imagine you are looking for either x or <2. 

Equation
<1 + <2 = 180          Substitute the givens
124 + 2x + 4 = 180  Collect like terms on the left.
128 + 2x = 180         Subtract 128 from both sides
2x = 180 - 128          Collect like terms on the right   
2x = 52                     divide by 2
x = 52/2
x = 26 <<<<<<<<< answer

<1 = 124
<2 = 2x + 4 = 2*26 + 4
<2 = 52 + 4
<2 = 56  <<<<<<<< answer

We need choices if you want an exact answer.

a town has 2 fire engines operating independently . the probability that a specific engine is available when needed is 0.96. wha
tester [92]

Answer:

The probability that neither is available when needed

P(A n B)^{c} = 0.04  

Step-by-step explanation:

A town has 2 fire engines operating independently

Given data  the probability that a specific engine is available when needed is 0.96.

Let A and B are the two events of two fire engines

given  P(A and B) = 0.96 ( given two engines are independent events so you have to select A and B)

Independent events : P( A n B) = P(A) P(B)

The probability that neither is available when needed

P(A n B)^{c} = 1- P(A n B)

P(A n B)^{c} = 1- 0.96 = 0.04
