Angle 2 is 110° and the other angles are 70°
Answer:
7.81mph
Step-by-step explanation:
Using the pythagoras theorem;
resultant r is expressed as;
r² = 5² + 6²
r² = 25 + 36
r² = 61
r =√61
r = 7.81mph
Hence the resultant speed is 7.81mph
Answer:
x = 1
Step-by-step explanation:
1. Expand.
6x − 18 + 10 = 8x − 10
2. Simplify 6x − 18 + 10 to 6x − 8.
6x − 8 = 8x − 10
3. Subtract 6x from both sides.
−8 = 8x − 10 − 6x
4. Simplify 8x − 10 − 6x to 2x − 10.
−8 = 2x − 10
5. Add 10 to both sides.
−8 + 10 = 2x
6. Simplify −8 + 10 to 2.
2 = 2x
7. Divide both sides by 2.
1 = x
8. Switch sides.
x = 1
