What is the value of x?​

Mathematics
1 answer:
Sladkaya [172]3 years ago
5 0

Answer:

The value of x is 8 cm

Step-by-step explanation:

we can see that there are two triangles

smaller triangle and larger triangle

and both triangles are similar

so, the ratio of their sides must be equal

we get

now, we can solve for x

we can cross multiply

Divide both sides by 5

Subtract both sides by 13

divide both sides by 2

Answer:

This is essentially the third identical question that you posted with the same

type of solution ... if you look at the previous question you asked and the explanation.. you will see that the red line crosses a corner of a box at (4,20)

4 cups =  20 pralines thus the number you are looking for is 20/4 = 5

Step-by-step explanation:

lets try this "story" to explain...

assume that you can walk 3 miles in 1 hour

this means that at 0 hr you go 0 miles , 1 hr you go 3 miles etc

0,0

1,3

2,6

3,9

etc.

if you graph that you will have the red line in you graph, and the x values would be 0,1,2,3 with the y values being 0,3,6,9....

if you DIVIDE any of those points

3/1 ,6/2, 9,3 the result is always a "3" that is the speed that you are walking at

it is a CONSTANT (in this problem) ... note: if the speed is NOT constant then this basically becomes a calculus problem, ant an algebra one.

Answer:

6. 300 m^2

Step-by-step explanation:

Volume of triangular Pyramid = V = 1/3AH, where A=Area of the base, H=Height. So,

300 =1/3A*3

300 =1/3*3*A

300 =A, or

Area of the base =300 m^2.

AlexFokin [52]

Answer:

<h3>Q5</h3>

As the opposite angles of a cyclic quadrilateral, A is supplementary with C and B is supplementary with D.

In the trapezoid,  angle A is supplementary with D and angle B is  supplementary with C.

It means ∠A ≅ ∠B and ∠D ≅ ∠C

Now, ∠ABD ≅ ∠ACD as both angles intercept same arc AD.

<u>So we have:</u>

  • m∠B = m∠ABD + m∠DBC = 35° + 72° = 107°
  • and
  • m∠C = 180° - m∠B = 180° - 107° = 73°

So angles B and A are 107° and angles D and C are 73°

<h3>Q6</h3>

PXR is exterior angle of triangle XSR.

Angles Q and S are supplementary as opposite angles of a cyclic quadrilateral QPSR.

  • m∠PXR = m∠XRS + m∠XSR = 20° + (180° - 80°) = 120°
