Answer:
47.0
Step-by-step explanation:
In this right angle triangle, we are faced with a challenge of two sides. The opposite side and the adjacent side, hence the tangent is used.
Where it is the opposite side and hypothenus side, the sine is used and when it is the hypothenus side and adjacent side, the cosine is used.
Hence, we have tan62°=x/25
We cross multiply, to have
25(tan 62°)= x
x = 47.01816
In rounding up numbers, number 1 to 4 will be rounded up to zero, while numbers 5 to 9 will be rounded up to 1.
Rounding up 47.01816 to the nearest tenth. The tenth value is the figure is 0, before it we have 1, which is to hundredth. 1 will be rounded up to zero.
So we have 47.0
The value of x is –7.
Solution:
Given expression:

Let us factor
.

Substitute this in the fraction.

To make the denominator same, multiply and divide the first term by (x +1).

Denominators are same, you can add the fractions.


Cancel the common term in the numerator and denominator.

Multiply the fractions.


The expression is simplified to one rational expression.
Suppose the expression is equal to 0.

Do cross multiplication.

Any number or variable multiplied by 0 gives 0.

Subtract 7 from both sides of the equation.

x = –7
The value of x is –7.
89+90=171. keep in mind that increased or increased by means to add
