M∠1 + m∠2 + m∠3 = 360
         y + 110 + 90 = 360
                 y + 200 = 360
                     - 200 - 200 
                           y = 160

It is the answer because it shows that the first one is 110 degrees and the second one 90 degrees, making a total of 200 degrees; since the angles have a total of 360 degrees, the value of y is 160 degrees.

Angelina_Jolie [31]

Answer:∠M in the pre-image corresponds to ∠B in the image.

Step-by-step explanation:

When  we look at the figures , we can see that the three vertices B , C , D are one side as vertices to M , N  ,O .

Clearly , vertex C corresponds to vertex N ( presents in the middle )

Also, point B is at the right from point C .In  Figure L M N O P , vertex M is at the right from vertex N .Thus , vertex M corresponds the vertex B.

It means ∠M in the pre-image corresponds to ∠B in the image.

brain list this answer thankyou:)

The circle at the right represents a planet. The radius of the planet is about 6300 km. Find the distance d to the horizon that
faust18 [17]

Answer:

224.54 km

Step-by-step explanation:

A right triangle is formed, where h + r = 4 + 6300 = 6304 km is the hypotenuse, r = 6300 km is one leg and d is the other leg. By Pythagorean theorem:

6304² = 6300² + d²

d² = 6304² - 6300²

d = √50416

d = 224.54 km
