Answer:
x=88, so it is acute.
Step-by-step explanation:
The two known angles are 45 degrees and 47 degrees. We know that in a triangle, the three angles always add up to 180 degrees.
This means that the third angle is 180-(45+47), or 180-92, or 88. So, the third angle is 88 degrees.
Acute triangles are when all the angles are less than 90. Right is when one angle is exactly 90. Obtuse is when one is more than 90. 88, 45, and 47 are all less than 90, so it is an acute triangle.
Answer:
The correct answer is a) 16
Step-by-step explanation:
To find this first distribute the interior negative to both terms in the parenthesis.
9 - {x - (7 + x)}
9 - {x - 7 - x}
Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.
16
When solving problems like these, the easiest thing to do is either turn both fractions into decimals or into fractions with a common denominator.
So 3/4 = 0.75 OR 9/12
And 2/3 = .666 OR 8/12
In solving the actual question, you're looking for the store that gives the better deal, meaning that they sell MORE apples for LESS.
The first store sells 9/12 of a bushel for $9 and the second store sells 8/12 of a bushel for $8.
The answer is the first store which sells 3/4 of a bushel for $9.
