For the bubble numbers put the second box in there, and for the chart put the first box.
The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:
... d = √((3 in)² +(13 in)²) = √(9+169) in = √178 in
The tangent of the angle you want to find is the ratio of the height of the box to this length:
... tan(α) = 4/√178
Taking the arctangent, we have
... α = arctan(4/√178) ≈ 0.291285 radians
All the triangles are isosceles meaning that they have to sides that are equal
Speed of object is 80 km/hr
Step-by-step explanation:
- Step 1: Formula for Speed = Distance/Time
Given Distance = 120 km and Time = 90 min
- Step 2: Convert given data into SI units.
Time = 90 min = 90/60 hours = 3/2 = 1.5 hours
- Step 3: Substitute in the formula
Speed = 120 km /1.5 hrs
= 1200/15 = 80 km/hr
