Answer:
7: 4 and 6
8: 8 and 2
9: 8 and 6
10: 3 and 6
11: x=3
Step-by-step explanation:
Answer:
the greatest possible value for x is 6
Explanation:
Assume that the sides of the triangle are:
a = x
b = 3x
c = 20
We are given that c is the longest side.
For the triangle to be obtuse:
c^2 > a^2 + b^2
Substitute with the values of a, b and c and solve for x as follows:
c^2 > a^2 + b^2
(20)^2 > (x)^2 + (3x)^2
400 > x^2 + 9x^2
400 > 10 x^2
40 > x^2
Now, we will get the zeros of the function. This means that we will solve for x^2 = 40 as follows:
x^2 = 40
x = + or - √40
either x = 6.32
Or x = -6.32
Since we want x^2 < 40, therefore, the greatest possible value for x to satisfy this condition is 6
Hope this helps :)
Answer:
78
Step-by-step explanation:
Answer:
angle B=122degree
Step-by-step explanation:
straight line AC =180degree, then 180-(21+37)=122 degree
a=b*sinA/sinB=84.5
c=b*sinC/sinB=141.9
Answer:
<h3>
3.375 Bags</h3>
Step-by-step explanation:
Convert 9 into an improper fraction. Specifically 27/3. Then you would convert 2 2/3 into an improper fractions as well. To get 8/3. Next you will divide 27/3 by 8/3 to get 27/8. We get 27/8 because we end up multipliying 27/3 by the receprical of 8/3. Then if you simplify you get 3.375 as your answer.
