Angles in a triangle add to 180 degrees, a quadrilateral 360 degrees, a pentagon 540 degrees and a hexagon 720 degrees.

y + 110 + 75 + 170 + 90 + 130 = 720

y = 720 - 575 = 145 degrees

This is a hexagon and the sum of its internal angles = 720 degrees.

Therefore m < y =  720 - (110 + 75 + 170 + 90 + 130)  

=   145 degrees  (answer).

990 minutes

Step-by-step explanation:

We know the unit rate is 11. So convert the hours into minutes. 1 hours is 60 minutes and half an hour is 30 minutes.

60 + 30 = 90

If it takes 11 minutes per minute 90 times 11 = 990

Length of KL is 17 units

Given that;

L is mid point of KM

KL = 2x - 3

LM = x + 7

Find:

Length of KL

Computation:

We know that,

L is mid point of KM

So,

KL = LM

2x - 3 = x + 7

2x - x = 7 + 3

x = 10

So,

Length of KL = 2x - 3

Length of KL = 2(10) - 3

Length of KL = 20 - 3

Length of KL = 17 units
