What value of x will make the equation below true?
X - 15 = 12

Answer:

x = 4.5

Step-by-step explanation:

Angle B = angle C because it is an isosceles triangle.

3x32 = 87-2x

96 = 87-2x

reduce:

9 = 2x

x = 4.5

An isosceles triangle is one with two equal-length sides. The value of x is 11.

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

Since in an isosceles triangle, the angle made by the equal sides and the base are equal, therefore, we can write,

∠B = ∠C

3x + 32 = 87 - 2x

3x + 2x = 87 - 32

5x = 55

x = 11

Hence, the value of x is 11.

Answer:

Step-by-step explanation:

A=s^2=64

s=8m

d^2=x^2+y^2, since it is a square x=y=8 then

d^2=2x^2

d^2=2(8^2)

d^2=128

d=11.3

So diagonal is approximately 11m

D. Neither congruent nor similar.

Step-by-step explanation:

Plato/Edmentum Answer

Given figures are neither congruent nor similar.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

We must compare the equivalent sides and angles of two figures in order to determine if they are congruent or comparable.

As congruent figures are the same in size and shape, their corresponding sides and angles are also identical in size. We simply need to identify one set of related sides or angles that are not equal to demonstrate that two figures are not congruent.

Comparable figures have the same form but different sizes, therefore their corresponding sides are proportionate even though their corresponding angles are equal in size. Finding one pair of matching angles that are not equal or a pair of corresponding sides that are not proportional will demonstrate that two figures are not similar.

Answer:

200 cm (or 2 meters) or 80% of the original 250 cm is left.  let me know if you have any questions.  

Step-by-step explanation:

I'm not sure if that's asking for an exact amount or percent, so I will do both.

The trick either way is to match units.  we have meters and centimeters.  You could make either one match the other.  so 2.5 m is 250 cm and 50 cm is .5 m.

You do have to know how many centimeters is in a meter, but once you know that you can set up unit conversions, which are super simple.

there are 100 cm in a m.  a unit conversion is basically a fraction that cancels out units.  starting with 2.5 m we want to cancel out m so the fraction we use has the m part in the denominator.  so 2.5m * (100 cm)/(1 m).  (100 cm)/(1 m) is the unit conversion, and just like variables the m in the denominator cancles out the m in the starting value so it turns into 2.5 * 100 cm/1 = 250 cm.

similarly to go from 50 cm to meters you make the unit conversion have cm in the denominator.  so 50 cm * (1 m)/(100 cm) = .5 m.  again, the cm int he denominator cancels out the cm in the unit being multiplied.  Let me knwo if this is still not clear.

Anyway, now we have the numbers we need.  let's make them all cm, I think using the smallest unit is usually easiest.  so that's 250 cm total and 50 cm used.

In pure numbers, that means 200 cm is left (which is 2 meters) after 50 cm gets used.

percents is a little trickier.  if 250 is 100% then 50 is 20%, which you can get by doing 50/250.  if you do not know, a fraction a/b gives you the percent a is of b.  Or rather it gives you a decimal, and if you multiply it by 100 it gives you the percent.

anyway, if 20% is used then 80% is left.  if you did 200/250 you would get that.
