Answer:
BC = 2
Step-by-step explanation:
We first need to use triangle BAD to find BD,
BD is the hypotenuse, so use pythagorean theorem...
(√23)² + (√13)² = (BD)²
23 + 13 = (BD)²
36 = (BD)²
6 = BD
Now BD is the hypotenuse of triangle BCD, so use pythagorean theorem agian to find BC
(4√2)² + (BC)² = 6²
32 + (BC)² = 36
(BC)² = 4
BC = 2
Answer:
Step-by-step explanation:
A=30 and the other one is 25
Step-by-step explanation:
To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.
Answer:
9
Explanation:
9 root 2 = root 81 x root 2 = root 162
Root 162 = 12.7279220614
9^2 + b^2 = 12.7279220614^2
81 + b^2 = 162
b^2 = 81
Root both
B = 9
Answer:
72
Step-by-step explanation:
Stage A has 6 outcomes, then B has 4 and C has 3
Take for example only 1 outcome of A, it will have 4 outcomes of B and each outcome of B will have 3 outcomes.
Then a single outcome of A has a total of 12 outcomes (4*3)
Writing it in a way A, B, C:
1,1,1
1,1,2
1,1,3
1,2,1
1,2,2
1,2,3
1,3,1
1,3,2
1,3,3
1,4,1
1,4,2
1,4,3
This is only taking in consideration 1 outcome of A, A has a total of 6 outcomes.
The total of outcomes in the experiment = 6*12=72
