Answer:
d
Step-by-step explanation:
Answer:
Since it's a right angled triangle,
taking 61 as reference angle,
cos61 = b/h
or, cos61 = b/8
or, b = cos61.8
so, b = 3.9 feet
The bottom of the ladder is 3.9 feet away from the side of the house.
Answer:
5
Step-by-step explanation:
Since the two sides of the triangle have equal opposite angles , they will be equal .
Since sides opposite to equal angles are equal.
Using this concept ,
=> 3x -4 = 2x + 1
=> 3x - 2x = 4 + 1
=> x = 5
Answer:
one solution
Step-by-step explanation:
both equations equal out to y=-4x+6
The length of UV is 19.7 ft.
<u>Solution:</u>
The given 
is a right triangle because W is 90 degrees. VW is adjacent to V and UV is the hypotenuse. Adjacent any hypotenuse use the cosine function.
Refer the image attached below for the image of the triangle.
plug in known values
The value of cos(72°) is 0.309
On substituting the above value in (1) we get,
Therefore, the required measure is 19.7 ft.
