Answer:

Step-by-step explanation:

It is not a scalene triangle because a scalene triangle has no sides equal and the triangle shown has 3 equal sides.

Answer:

b) this sketch is an equilateral triangle

Step-by-step explanation:

the sketch shown is an equilateral triangle, in which all three of it's sides are equal lengths as well as it's angles!

a scalene triangle's lengths are all different, as well as it's angles

hope this helps :)

Help two helpless triangles?

Illusion [34]

Answer:

see below

Step-by-step explanation:

Angle ACE = DCE since they are vertical angles

Angle A = Angle E parallel lines cut by a transversal form congruent alternate interior angles

Angle B = Angle D parallel lines cut by a transversal form congruent alternate interior angles

When all three angles are equal, the triangles are similar.

We can use ratios to find DE

DE CE

------- = ----------

AB AC

DE 8

------- = ----------

12 10

Using cross products

10 DE = 8*12

10 DE = 96

Divide by 10

DE = 9.6

Which graph correctly represents the relationship between arc length and the measure of the corresponding central angle on a cir

user100 [1]

Any smooth curve connecting two points is called an arc. The correct option is c.

<h3>What is the Length of an Arc?</h3>

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

$\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}$

where

θ is the angle, that arc creates at the centre of the circle in degree.

If the central angle has a measure of π/2(90°), then the length of the arc will be one-fourth of the total, while if the measure of the angle is π(180°), then the length of the arc will be half of the total.

Similarly, if the measure of the angle is 3π/4, then the length of the arc will be three-fourth of the total, while if the measure of the angle is 2π(360°), then the length of the arc will be 2πr.

Hence, the correct option is c.

( x - 2 ) ( x + 2 ) ( x bình + 4 ) - ( x bình - 2 ) ( x bình + 3 )

kifflom [539]

Answer:

( x - 2 ) ( x + 2 ) ( x² + 4 ) - ( x² - 2 ) ( x² + 3 )

(x²– 4) (x²+4) – (x⁴ + x² – 6)

( x⁴ – 16 ) – ( x⁴ + x² – 6 )

( x⁴ – 16 ) + ( – x⁴ – x² + 6 )

– x² – 10
