Answer:
B
Step-by-step explanation:
Because alternate interior angles are congruent in parallel lines, the angle next to the 25° in the right triangle is 85 - 25 = 60° which makes the other angle in the right triangle 180 - 90 - 60 = 30°. Since they form a straight angle, we can write x + 30 + 85 = 180 → x + 115 = 180 → x = 65°.
I believe it would be 3 but dont take my word
y = ( x + 9 )^2 - 2

Hey there,
In order to solve this equation we are going to subtract 2/3 by 3/4.
To add or subtract fractions we need to make sure that they have a common denominator:
- 2/3 and 3/4 (common denominator would be 12) so 8/12 and 9/12
Now that the denominators are the same we can subtract the two fractions:
- 9/12 - 8/12 would equal to 1/12
That means that 1/12th of the wall still needs to be done.
Therefore 8/12 of the wall had been painted green at the end of Tuesday.
Hope I helped,
Amna
