Find the m∡B to the nearest tenth of a degree if cos B = 0.8926 and ∡B is an acute angle
mrs_skeptik [129]

Answer:

26.8°

Step-by-step explanation:

The cosine of an angle is the ratio of the adjacent side of the triangle in which the angle is formed to the hypotenuses side of the triangle. The cosine of the angle gives the ratio of these sides. However, the arc cosine of the ratio gives the angle measured in degrees.

If cos B = 0.8926

then arc cosine 0.8926  which may be expressed as cos-1 0.8926 will give the value of B.

B = cos-1 0.8926

= 26.8°

I=0.13x+1025 A textbook salesperson's monthly income depends on the amount of his sales. His monthly income is a salary of $1025
Snezhnost [94]

Answer:

l = 0.13x+1025

Step-by-step explanation:

Let the monthly sales be x

Monthly income = $1025 + 13% of monthly sales

Monthly income = $1025 + 0.13x

Since l  represent the monthly income

l = 1025+0.13x

Rearrange

l = 0.13x + 1025

Hence the linear equation representing the statement is l = 0.13x+1025
