B) 70°
C) 90°
D) 120°
Answer: A)
Step-by-step explanation:
Given: ΔABC is similar to ΔDEF
Therefore,
∠A=∠D=50°
∠B=∠E=70°
∠C=∠F
Using Angle sum property, in triangle ABC, we get
The angle sum property of a triangle says that, the sum of all the angles in a triangle is .
Answer:
3.54 and 1.04
Step-by-step explanation:
Given:
Two towns are 1,100 miles apart.
A group of hikers Starts from each town and walks down the trail toward each other..
They meet after a total hiking time of 240 hours.
If one group travels 2 1/2 mile per hour slower than the other group.
Question asked:
Find the rate of each group.
Solution:
Let speed of faster hiker =
Speed of slower hiker =
As we know:
Total distance between two town = Total combined speed of both hikers Total combined time taken
Speed of faster hiker = = 3.54 miles per hour.
Speed of slower hiker = =
Therefore, speed of faster hiker is 3.54 miles per hour and speed of slower hiker is 1.04 miles per hour.
