Answer:

n=11.5

Step-by-step explanation:

Given:

The two expressions are:

(ny+25.7)+(-45.2y+13.9)=(n-45.2)y+39.6

-33.7y+39.6

If the above 2 expressions are equivalent, then the coefficients of y should be equal for both the expressions.

The coefficient of y in the first expression is:

(n-45.2).

The coefficient of y in the second expression is:

-33.7.

Therefore,

n-45.2=-33.7\\n=-33.7+45.2=11.5

What is the length x of the right triangle, rounded to the nearest<br> tenth?
Zarrin [17]

Answer:

109.5; B

Step-by-step explanation:

From your identity,

CosA = adjacent/ hypothenus

A represent an arbitrary angle between the sides in question.

In the question above, A=64

Hypothenus is the longest side and adjacent is the side just below the angle .

In the above case,

Hypothenus= X

adjacent =48

This means;

Cos64 = 48 /X

X = 48 / cos64; [ from cross multiplication and diving through by cos64]

X = 48 /0.4383 [ cos64 in radian = 0.4383]

= 109.51

= 109.5 to the nearest tenth.

Note( do your calculation of angle in radian or else, you won't get the answer)
