Answer:
1/2 since there's always a fifty-fifty chance.
Use the Pythagorean Theorem:
A²+B²=C²
6²+5²=C²
36+25=C²
61=C²
√61=C
So the answer is C.
I could be wrong (and I apologize if I am), but I believe these are the answers to your questions.
1.) Angle 4
2.) Angle 6
3.) Angle 10
4.) 30 degrees
5.) 48 degrees
6.) 55 degrees
7.) 68 degrees
8.) 148 degrees
9.) 102 degrees
10.) 38 degrees
If I turn out to be correct, then I am happy I was able to help you.
Your answer would be 4x-7=-3(3+4x) because it only has one solution which is x= -1/8
I believe it is 20 since I did 4+4+4+4+4 =20 since each shirt has 4 mixes it could have with the pants. Hope I helped
