first I would find all the ways to make 9
6+3=9
5+4
then I would find all the ways to make 10
6+4=10
5+5=10
then I would find all the ways to make 11
6+5
then I would find all the ways to make 12
6+6=12
then add the number of possibilities
9 + 10 + 11 + 12 = 6
There are 6 different ways to make a sum of 9 or more
Answer:
Step-by-step explanation:
8x-2
8x=-2
/8
x=-1/4
So you would do .39 times .39
that is .1521
If you round it is .152
.152 times 100 equals 15.2%
Answer:
The measure of the third angle is a 90 degrees
Step-by-step explanation:
Let
A and B ----> two complementary angles in a triangle
C ---> the measure of the third angle in a triangle
we know that
If two angles are complementary, then their sum is equal to 90 degrees
so
---> equation A
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
----> equation B
substitute equation A in equation B

solve for C
subtract 90 degrees both sides


therefore
we have a right triangle
