Which characteristics best describe an acute isosceles triangle?

2 answers:

4 0

Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees

We can rule out choice I since acut means less than 90

II is a possibility, but it doesn't best describe it

III. that is true, but it doesn't include the isocileese part

IV. that is true, but doesn't include the acute part

not sure, either III or IV

valina [46]

Answer:

$\large\boxed{y\leq8\to\{y\ |\ y\leq8\}\to y\in(-\infty,\ 8]}$

Step-by-step explanation:

$-1+4y\leq31\qquad\text{add 1 to both sides}\\\\-1+1+4y\leq31+1\\\\4y\leq32\qquad\text{divide both sides by 4}\\\\\dfrac{4y}{4}\leq\dfrac{32}{4}\\\\y\leq8$

The diameter of circle X is 15 centimeters. The diameter of circle Y is 20 centimeters. Which measurement is closest to the diff

valina [46]

The difference between the circumference of circle X and circumference of circle Y is 5π cm.

<h3>What is circumference of a circle?</h3>

This is the distance round a circle.

The circumference of circle X is calculated as follows;

$C_X = \pi d\\\\
C_X = 15\pi \ cm$

The circumference of circle Y is calculated as follows;

$C_Y = \pi d\\\\
C_Y = 20 \pi \ cm$

The difference between the circumference of circle X and circumference of circle Y is calculated as follows;

$C_Y - C_X = 20\pi - 15 \pi = 5\pi \ cm \\\\
$

Thus, the difference between the circumference of circle X and circumference of circle Y is 5π cm.

Find the value of each polynomial when (a) x=0 and (b)= -1<br> 15). x^2-5x-2

Trava [24]

A) Just plug 0 in for x:
0^2 -5(0) -2
0 -0 -2 = -2

b) plug -1 in for x:
(-1)^2 -5(-1)-2
1 + 5 - 2 = 6-2=4

The parallel sides are congruent, or equal in length, so

BC = AD
6-x = x+2
6-2 = x+x
4 = 2x
2x = 4
x = 2

If x = 2, then
BC = 6-x = 6-2 = 4
AD = x+2 = 2+2 = 4
meaning that the top and bottom parallel sides are each 4 units long

--------------------------------------------

Similarly, the opposite angles are congruent as well

Angle A = Angle C
100-y = 12+y
100-12 = y+y
88 = 2y
2y = 88
y = 44

If y = 44, then
angle A = 100-y = 100-44 = 56
angle C = 12+y = 12+44 = 56
