The sum of angles in any triangle is 180 degrees.

It is given <1+<3=154 degrees.

<1+<2+<3=180

Or <1+<3+<2=180

Substituting <1+<3=154 we have

154+<2=180

Subtracting 154 both sides <2=180-154

<2= 26 degrees

First option is right answer.

Two Angles are Supplementary when they add up to 180 degrees

Two Angles are complementary when they add up to 90 degrees

Given <1+<3 =154 So they are neither complementary or supplementary.

Answer:Neither

Novay_Z [31]

Answer:

probability that both passes a defective item is  0.8742‬

<h3>Step-by-step explanation:</h3>

probability that the first inspector misses is Pr( 1st misses)= 0.06

therefore the probability he does not miss is

Pr(1st passes)= 1 - Pr( 1st misses) = 1 - 0.06 = 0.94

probability that the second misses is Pr( 2nd misses) = 0.07

therefore probability that 2nd does not miss is

Pr( 2nd passes) = 1- Pr( 2nd misses) = 0.93

probability that both passes a defective item is  Pr(1st passes)*Pr( 2nd passes)

= 0.93*0.94 = 0.8742‬

A commercial aircraft gets the best fuel efficiency if it operates at a minimum altitude of 29,000 feet and a maximum altitude o
Semenov [28]

Answer:

A

Step-by-step explanation:

A is correct because if the minimum is 29,000 feet, x (the airplane altitutude) must be greater than or equal to 29,000 ft. Since the maximum is 41,000 feet, x must be less than or equal to that number.

Cassandra assigns values to some of the measures of triangle ABC. If angle A measures 30°, a = 6, and b = 18, which is true?
Anna [14]

Answer:

The triangle does not exist because sin(A)/a can not be equal to sin(B)/b

Step-by-step explanation:

we know that

step 1

Find the measure of angle B

Applying the law of sines

\frac{sin(A)}{a}=\frac{sin(B)}{b}

we have

A=30\°

sin(30\°)=1/2

a=6\ units

b=18\ units

substitute

\frac{(1/2)}{6}=\frac{sin(B)}{18}

\frac{1}{12}=\frac{sin(B)}{18}

sin(B)=\frac{18}{12}

sin(B)=\frac{3}{2}=1.5

Remember that the value of sine can not be greater than 1

therefore

The triangle does not exist because sin(A)/a can not be equal to sin(B)/b

Select the property of equality used to arrive at the conclusion.
artcher [175]

Answer:

A

Step-by-step explanation:

The statement "If x = 3, then x^2 = 3x" was formed by multiplying x = 3 by x on both sides. Thus x = 3 becomes x*x=3*x. This simplifies to x^2 = 3x. This property is the multiplication property of equality.
