Answer:
Option 2nd is correct.
Step-by-step explanation:
In right angle triangle:
Pythagoras theorem follows which is:
Here, c= hypotenuse b is one side and a is the other side.
Therefore, according to Pythagoras theorem Option 1,3 and 4 are discarded.
Option 2nd is correct because KL=EF and triangle KLM and EFG follows Pythagoras theorem which makes them a right angle triangle.
Answer:
1.04 mill
Step-by-step explanation:
15 inches to mill = 381
= 1.04 ( rounded )
Answer:
θ = 
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ = 
Sin θ = 
= 0.5
θ = 
0.5
θ =
Thus, the angle of elevation from the base to the top of the mountain is .
Step-by-step explanation:
1.5 mi = 2 and 1/4 min
In 43 minutes:
43 ÷ 2.15 = 20 2.15 = 2 and 1/4 min
Now you have to multiply 1.5 by 20
1.5 x 20 = 30
In 1 hour (60 minutes):
60 ÷ 2.15 = 27.9
Now you have to multiply 1.5 by 27.9
1.5 x 27.9 = 41.85

Answer:
x=28
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees
Therefore,
79+73+x=180
Combine like terms by adding 79 and 73
152+x=180
To solve for x, get x by itself. Since 152 is being added to x, subtract 152 from both sides. This will cancel the 152, and leave x by itself.
152-152+x=180-152
x=28
So, x is equal to 28 degrees
