For a project in his Geometry class, Mamadou uses a mirror on the ground to measure the height of his school's football goalpost
andreev551 [17]

Answer:

Height of the goalpost is 9.25 m.

Step-by-step explanation:

As per the rule of reflection in physics,

Angle of incidence = Angle of reflection

As we can see in the picture attached, both the angles (θ) are equal.

m∠ACB = m∠ECD = 90° - θ

m∠ABC = m∠ADC = 90°

Therefore, both the triangles ΔABC and ΔEDC will be similar.

And by the property of similar triangles, their corresponding sides will be proportional.

\frac{AB}{ED}= \frac{CB}{CD}

\frac{1.75}{ED}=\frac{2.6}{13.75}

ED = \frac{1.75\times 13.75}{2.6}

ED = 9.25 m

Height of the goalpost is 9.25 m.

For* 15-16 find the number of sides if a polygon has the given measure for each interior angle,
salantis [7]

Answer:

15. d) 36

16. b) 20

17. d) 180

18. b) 50

19. c) 360

20. b) 60

Step-by-step explanation:

To find the number of sides a polygon has giving an interior angle, use the equation:

(number of sides - 2)*180/(number of sides) = measure of interior angle

<em>15. </em>(n = number of sides)

((n-2)*180)/n = 170

180n-360 = 170n

10n = 360

n = 36 (d)

<em>16.</em> (n = number of sides)

((n-2)*180)/n = 162

180n-360 = 162n

18n = 360

n = 20 (b)

<em>17.</em> The sum of the interior angles of a triangle is always 180 (d)

<em>18.</em> 180-60-70 = 50 (b)

<em>19.</em> The sum of the interior angles of a quadrilateral is always 360 (c)

<em>20.</em> 360-120-90-90 = 60 (b)

Multipaction decimals
krok68 [10]
Multiplying decimals is basically the same thing as multiplying whole numbers, but a little tougher. For example, 3 X 2 = 6, which is quite easy, but yoou might need more education to solve 3.6 X 2.6 = 9.36

I don’t understand this PLEASE HELP
Marta_Voda [28]

Answer:

13

Step-by-step explanation:

If BE is the bisector then m<ABE must be equal to m<EBC

So we make the equation like this :

2x + 20 = 4x - 6

➡

20+6 = 4x-2x

➡

26=2x

➡

x = 13
