Answer:

Angle measurements of 35°, 35°, and 110°

Angle measurements of 40°, 60°, and 80°

Step-by-step explanation:

If you specify only the three angles, you can have an infinite number of similar triangles of different sizes.

A is wrong. There can be only one triangle in which all three side lengths are specified.

C is wrong. The angles do not add up to 180°.

<h2>Answer:</h2>

The descriptions which can describe more than one triangle is:

  • angle measurements of 35°,35° and 110°.
  • angle measurements of 40°,60° and 80°.
<h2>Step-by-step explanation:</h2>
  • The three given side lengths form a triangle if the sum of any 2 sides is greater than the length of the third side.
  • Also, all the three given angle measure form a triangle if the sum of all the three angles is equal to 180 degree.
  • We know that with the help of given side three lengths of a triangle a unique triangle is formed.
  • and with the help of given three angle measures of a triangle more than one triangle is possible with distinct side length.

a)

Side lengths 6 ft, 8 ft and 10 ft.

First we check whether it form a triangle or not:

6+8=14>10

8+10=18>6

and

6+10=16>8

Yes, these side lengths form a triangle.

With the help of this only one unique triangle is possible.

b)

angle measurements of 35°,35° and 110°

First we check the sum of the angles:

35°+35°+110°=180°

Hence, more than one triangle is possible.

c)

angle measurements of 30°,40° and 50°

First we check the sum of these angles:

30°+40°+50°=120°≠180°

Hence, these angles measure do not form a triangle.

d)

angle measurements of 40°,60° and 80°

First we check the sum of these angles:

40°+60°+80°=180°.

Hence, more than one triangle is possible.

e)

side length of 4 cm, 6 cm and 9 cm.

First we check whether it form a triangle or not:

4+6=10>9

6+9=15>4

and

4+9=13>6

Hence, a unique triangle will be formed.

Circumference and Area questions look at the picture
Helga [31]

Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².

π≈3.14

A. C=πd

Simply plug in the numbers into the formula.

Diameter=Radius*2

17*2=34

C=34(π)

B. (π)(5²)

Plug in the numbers into the formula. Remember that half of the diameter is the radius.

C.  (π)(4.5)

There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.

The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.

D. (π)(6.5²)

Remember that the formula for calculating the area of a circle is πr².

Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.

(π)(6.5²)

Therefore, the last answer choice is the correct answer.

What is the value of x? Show your work.
Vilka [71]

The small arcs inside the triangle show that they are similar, so first find the ratio between the similar sides that both have given lengths.

JK is 25, and MN is 30.


30/25 = 1.2


This means the larger triangle is 1.2 times the size of the smaller one.


So MP needs to equal 1.2 x the length of JL:

JL = 20

20 * 1.2 = 24


Now you have 4x-4 = 24

Now silve for x:

Add 4 to each side:

4x = 28

Divide both sides by 4:

x = 28 / 4

x = 7

Help me plz this is hard will give points
baherus [9]

Answer:

C = 14pi

Step-by-step explanation:

C = pi d

The radius is 7 so the diameter is

d = 2r

d = 2*7

=14

C = pi *14

C = 14pi
