A straight line is 180°. See the obtuse angle with the "155°"? There is straight line that starts at the "8)" and goes to the "?". Therefor, that 155° you see can be subtracted from 180. 180-155=25, which means the very acute angle in the triangle is 25<span>°. The three angles in a triangle have to equal 180, and you already have 60 and 25. 60+25 is 85. 180-85 is 95. This means that the bottom right angle within the triangle is 95. Well, if you know angle rules, then you'll know that angle "?" is also 95, because it is perpendicular to the bottom right angle within the triangle. :) Hoped this helped! Sorry I took so long to write it... I had to go to the store before I could finish xD</span>

Answer:
y=7
Step-by-step explanation:
Answer:
A statement, also known as an axiom, which is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived.
Step-by-step explanation:
The Addition Postulate: If you have one apple and Sally has one apple, when you both add the same quantity to your existing number of apples, you'll still have the same number of apples. Using algebra, the postulate states:
If x = y, then x + 4 = y + 4
The Subtraction Postulate: If you have ten apples and Sally has ten apples, when you both subtract the same quantity of apples from your existing number of apples, you'll still have the same number of apples.
If x = y, then x - 3 = y - 3
Without being repetitive, these same principles apply to both multiplication and division.
The Multiplication Postulate: If x = y, then x * 3 = y * 3
The Division Postulate: If x = y, then x / 7 = y / 7
C is 6 & d is 9
6+9=15
3(6)+2(9)=36
18 + 18 = 37
