Answer:
X = 45
Step-by-step explanation:
90 + X + A = 180 (angles of a triangle sum to 180)
90 + X + 45 = 180
X = 45
Answer:
length of one leg of the triangle is 64 cm.
Step-by-step explanation:
Given : The hypotenuse of a 45°-45°-90° triangle measures 128 cm.
To find : What is the length of one leg of the triangle.
Solution : We have given that hypotenuse of a 45°-45°-90° triangle measures 128 cm.
By the 45°-45°-90° triangle rule ,
Perpendicular sides (legs) are equal .
Hypotenuse = √2 × either perpendicular side ( leg ).
128 = √2 × leg .
We can write 128 as 64 √2 and substitute in above
64√2 = √2 leg.
On dividing by √2 both sides and switching sides.
leg = 64 cm .
Therefore, length of one leg of the triangle is 64 cm.
Let the Distance between A and B be : C km
Given : The Man Travels from A to B at a Speed 4 km/h
⇒ The Man Travels 4 km in One Hour during his Journey from A to B
⇒ 
⇒ 
Given : The Man Travels from B to A at a Speed 6 km/h
⇒ The Man Travels 6 km in One Hour during his Journey from B to A
⇒ 
⇒ 
⇒ 
We know that One Hour contains 60 Minutes
⇒ The Total Time taken by Man = 
Given Total Time Taken by Man is 45 Minutes
⇒ 25C = 45
⇒ 
But the Total Distance Traveled by the Man is 2C
⇒ 2C = 2 × 1.8 = 3.6 km
⇒ The Total Distance Traveled by the Man is 3.6 km
Answer:
28
Step-by-step explanation:
This is bc 7 plus 28 is equal to 35.
