Step-by-step explanation:

I think you went through right-angled triangles and Pythagoras before you stated these topics ?

then it is really easy.

as the graphic suggests already : the inner height of the cone, the radius (half of the diameter) of the base circle and the mantle length l build a right-angled triangle, and we can use Pythagoras to get l :

l² = 7² + (14/2)² = 7² + 7² = 2×49 = 98

l = sqrt(98) ft

FYI : which could be further simplified as 98 = 2×49 :

sqrt(98) = sqrt(2×49) = 7×sqrt(2)

I don’t know how to do this please helppp

Answer:

Given the 2 values, height and the base, of these 2 triangles, we can assume that they are similar (meaning they share the same angles) as we have no other information to determine the height of the tree.

Therefore, if these triangles are similar, their corresponding sides are proportional. In other words, PZ/RT = QZ/ST or RT/PZ=ST/QZ

Hence, if we find the ratio of this, we can use it to find the side h

QZ/ST=PZ/RT

48/12=PZ/4

PZ/4=48/12

(PZ/4)3=48/12

PZ(3)/12=48/12

48/3=16

16=PZ.

-6x-7=3x+11 how to solve this problem

Shalnov [3]

You have to get the x to one side so you'll subtract 3x from -6x and 3x from 3x, the 3x will cancel out and -6x - 3x is -9x-7=11, you have to add 7 from both sides the 7+7 cancels out and also add 11+7 which leaves -9x=18, you have to divide -9x/-9 and do 18/-9, which gets you x=-2. Here's the work shown if you didn't what i said...
-6x-7=3x+11
-3x -3x
-9x-7=11
+7 +7
-9x=18
-9 -9
x=-2

A midsegment connecting two sides of a triangle is parallel to the third side and equal to which

lys-0071 [83]

Answer:

One half (1/2) the measurement of the third side

Step-by-step explanation:

Mid segment theorem defines the relationship between the constructed line joining the midpoint of two sides of a triangle, and parallel to the third side of the triangle which is also called the midsegment

Whereby the angles are defined by the proportion of the sides, the midsegment will have a length which is half the measurement of the length of the third side.

Using the following picture which side is the hypotenuse?

mylen [45]

Hi!

A hypotenuse is the longest leg in a right triangle.

A right triangle is a triangle that has one 90 degree angle.

The hypotenuse is always directly across from the right angle.

In pictures, right angles are represented by a square.

Therefore, the side with the hypotenuse is side 3, because we can see that the angle between side 1 and side 2 is the right angle, and the hypotenuse would be directly across.
