If theta is an acute​ angle, solve the equation tangent theta equals four fifths

Mathematics

rusak2 [61]3 years ago

Answer:

\theta=38.7\degree

Step-by-step explanation:

We want to solve \tan \theta=\frac{4}{5} given that \theta is acute.

We take tangent inverse of both sides to get:

\theta=\tan^{-1}(\frac{4}{5})

Now set your calculator to degree mode and evaluate \tan^{-1}(\frac{4}{5}) to obtain:

\theta=38.6598\degree

To one decimal place, we have;

\theta=38.7\degree

the angle between two lines is 60 degree. if the slope of one of them is 1. find the slope of other line​
Degger [83]

Answer:

-3.73

Step-by-step explanation:

solution:

Given:

Angle between two lines=60⁰

slope of first line=1

Or, tanA=1

Or, A= tan inverse (1)

so, A=45⁰

so, angle of inclination of first line=45⁰

Now,

angle of inclination of second line= A+ 60⁰

= 45⁰+60⁰

=105⁰

so, slope of second line = tan105.

= -3.73

N is an odd number.
nikitadnepr [17]

Answer:

True:

D.

E.

F

Step-by-step explanation:

First, you should know that the square of any odd number is also odd.

The easiest way to go about this is to plug in an odd number for n. Lets use 3:

Plug 3 into A:

3^{2} -1=9-1=8

Plug 3 into B:

3(3-1)=9-3 = 6

Plug 3 into C:

(3-2)^{2} = 2^{2}  = 4

Plug 3 into D:

3^{2} +2 = 9+2=11

Plug 3 into E:

3(3-2) = 9-6 = 3

Plug 3 into F:

(3-2)^{2}=1^{2}  =1
