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

Mr. Garland bought 4 pounds of grapes for $8. How many pounds of grapes can he buy for $66.
Anna11 [10]

<u>Answer:</u>

  • 33 pounds of grapes can be brought for $66.

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

<u>4 pounds = $8</u>

  • => 1 pound = $2
  • => x pounds = $2x = $66
  • => x = 33
  • => 33 pounds = $66

Hence, <u>33 pounds of grapes can be brought for $66.</u>

Hoped this helped.

consider a quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1). determine the most accurate type of quadrilateral from the
Burka [1]

Answer:

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

Step-by-step explanation:

Considering the quadrilateral with vertices

  • d(0,0)
  • i(5,5)
  • n(8,4)
  • g(7,1)

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

From the figure a, it is clear that the quadrilateral has

  • Two pairs of sides
  • Each pair having two equal-length sides which are adjacent
  • The angles being equal where the two pairs meet
  • Diagonals as shown in dashed lines cross at right angles,  and one of the diagonals does bisect the other - cuts equally in half

Please check the attached figure a.

What is the value of x in the equation 3x- 4y =65, when y= 4?
Alexus [3.1K]
3x-4y=65

3x=65+4y

x=(65+4y)/3, when y=4

x=(65+4*4)/3

x=(65+16)/3

x=81/3

x=27
