Answer:
AB ≈ 7.10
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos65° = = =
Multiply both sides by AB
AB × cos65° = 3 ( divide both sides by cos65° )
AB = ≈ 7.10 ( to the nearest hundredth )
Answer:
x ≈ 18.28

Step-by-step explanation:
<u>Step 1: Define</u>
tan51° = x/14.8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Multiply 14.8 on both sides: 14.8tan51° = x
- Evaluate: 18.2765 = x
- Rewrite: x = 18.2765
- Round: x ≈ 18.28
M <3 + 138 =190
so m<3 = 180 -138 = 42
r ans t are parallel so m<3 = m<6 then m<6 = 42

Answer:
15 m/sec
1 km = 1000 m
1 hr = 60 min
1 min = 60 sec
1 hr = 60 × 60 sec
So, 15 m/sec = 15 × (60 × 60)/1000 km/hr
54 km/hr
