Answer:

17.3

Step-by-step explanation:

a² = b² + c² - 2bc cos A

t² = 11² + 14² - 2(11)(14) cos 87

t² = 121 + 196 - 308 (.052336)

t² = 300.88

t = 17.3

Negative 5 is fewer than 6 less than a number k
lara [203]

Answer:

k > 1 is the solution.

Step-by-step explanation:

We are given that 'Negative 5 is fewer than 6 less than a number k', so algebraically it means that - 5 < k - 6.

Then this is a linear inequality of single variable k and we have to solve it.

Now, we have

- 5 < k - 6

⇒ - 5 + 6 < k - 6 + 6 {Adding 6 to both sides}

⇒ 1 < k

⇒ k > 1

This is the solution of the given inequality. (Answer)

Alex drew a scale drawing of an auditorium. He used the scale 3 inches = 2 feet. If the stage is 30 inches in the drawing, how w
White raven [17]

Answer:

20 feet

Step-by-step explanation:

The scale is 3 inches is to 2 feet

As a ratio, it would be:

\dfrac{3}{2}

The question is what is the actual length of the stage if the drawing is 30 inches. All we need to do is find a ratio proportional to the scale ratio:

\dfrac{3inches}{2feet} = \dfrac{30inches}{xfeet}

Now to find the missing number, cross multiply the fractions first:

\dfrac{3}{2}=\dfrac{30}{x}

(3)(x)=(2)(30)

3x=60

Then solve for x:

3x=60

x=\dfrac{60}{3}

x=20

The answer is 20 feet

I need help finding m
Dafna1 [17]

Answer:

<A = 27 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

Tan A = opp side / adj side

Tan A = 2/4

Tan A = 1/2

Taking the inverse tan of each side

tan^-1 ( tan A) = tan ^-1 (1/2)

A =26.56505118

Rounding to the nearest  degree

A = 27
