Answer:
31 degrees
Step-by-step explanation:
Measure angles 1 and 3 are vertical angles, meaning they are equal which means 3 = 149 degrees
Angles 2 and 3 are adjacent and supplementary, meaning that their angles add up to 180.
1<u>8</u>0 - 149 = 31 degrees
The answer is 6. To answer this you would need to do 16.5/11 to get 1.5 (that's how much the rectangle got enlarged). Then you would do 4 times 1.5 to get your new height size, which is 6.
The average would be 666.43 or 666.4 if it needs to be rounded to the nearest tenth
These are the elements of the matrix
Elements of the first row are h11 h12 h13, of the second row h21 h22 h23.
Than we can conclude that element h23 worth 75.
Good luck!!!
