Answer: the perimeter is about 7 if you look at it
Step-by-step explanation:
Sin (angle) = opposite leg / hypotenuse
Sin(62) = 18/x
The answer is the third choice.
One of the other angles will also be 35°.
Because the sum of all the angles will equal to 360, and two of the angles are 35° and 35+35 is 100, the sum of the last two angles will be 260 because 360-100 is 260.
This means that since the last 2 angles are the same and they add up to 260, you divide 260 by 2 to get 130.
This means the last two angles are 130°.
The measures of all the other angles are 35°, 130° and 130° again.
Answer:
3 quarts
Step-by-step explanation:
First, find how many quarts of antifreeze is in the mixture.
0.4 x 6 = 2.4
Now, make it into a fraction by putting the antifreeze amount over the rest so:
2.4/6
Now add + a at the end of the numerator and bottom to make:
2.4 + a/ 6 + a.
Now, turn the percentage you want to strengthen or weaken the mixture into a percentage. So, 3/5.
Now, make it an expression by adding = 3/5 at the end of the equation.
2.4 + a/ 6 + a = 3/5
Now, use cross multiplication.
12 + 5a = 18 + 3a
Now, solve the equation.
12 + 5a = 18 + 3a
-3a. -3a
12 + 2a = 18
-12. -12
2a = 6
/2. /2
a = 3.
Therefore, the answer is 3 quarts.
