You lean a ladder 6.7 meters long against a wall. It makes a 63 degree angle with the level ground. How high up is the top of the ladder?
Answer:
1.12 meters
Step-by-step explanation:
sin(63)=x/6.7
6.7(sin(63))=x
x=1.12
By using the concept of reciprocal of fraction, the result obtained is -
Reciprocal of is
What is reciprocal of a fraction?
At first, it is important to know about fraction.
Suppose there is a collection of objects and a part of the collection has to be taken. The part which is taken is called fraction. In other words, part of a whole is called fraction.
The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.
For example: is a fraction. Here, 4 is the numerator of the fraction and 7 is the denominator of the fraction.
Let p be a fraction. Reciprocal of p is a fraction in which if the fraction is multiplied by p, the result obtained is 1 (multiplicative identity)
Here,
Let the reciprocal of be x
Reciprocal of is

1. Solve for x: 2x + 4 > 8x – 8
Answer:
Step-by-step explanation:
hello :
2x + 4 > 8x – 8 means : 2x-8x > -8-4
-6x > -12
now multiply by -1 : 6x < 12
x < 12/6
x < 2
-4x + 2y + 5 + 9a
Step-by-step explanation:
Coefficient of:
x = -4
y = 2
a = 9
Answer:
the ansssswer id2y, -9a
