HELP !!!!!!!!!!!!!!!!

Mathematics
1 answer:
Fantom [35]3 years ago
5 0

Answer:

∠2 = 51°

Step-by-step explanation:

The sum of supplementary angles = 180°

Equate the sum of the angles to 180 and solve for a

11a + 19 + 6a - 9 = 180

17a + 10 = 180 ( subtract 10 from both sides )

17a = 170 ( divide both sides by 17 )

a = 10

Hence

∠2 = (6 × 10) - 9 = 60 - 9 = 51°

In the figure, △ABC is similar to △DEF. what is m∠1
Nady [450]

Answer:

C. 139°

Step-by-step explanation:

Given:

m<A = 62°

m<B = 77°

Required:

Find m<1

Solution:

Since ∆ABC is similar to ∆DEF, therefore:

<A ≅ <D, which means m<D = 62°

<B ≅ <E, which means m<E = 77°

<C ≅ <F

Therefore, based on exterior angle theorem:

m<1 = m<D + m<E

m<1 = 62° + 77° (substitution)

m<1 = 139°

Solve in degrees. 0 &lt; θ &lt; 360<br> 1. tan θ = 3.5134
Temka [501]

Answer:

Therefore,

\theta=74.11\°\ or\ \theta=254.11\°

Step-by-step explanation:

Given:

0° < θ < 360°

tan θ = 3.5134

To Find:

θ in degrees = ?

Solution:

0° < θ < 360° .............Given

Means ' θ ' is between 0° and 360°

\tan \theta=3.5134 .............Given

Therefore,

\theta=\tan^{-1} (3.5134)

Also,

\tan (180+\theta)=\tan \theta

So  ' θ '  will have Two values for tan θ =3.5134

\therefore \theta=74.11\°\ or\ \theta=180+74.11=254.11\°

Therefore,

\theta=74.11\°\ or\ \theta=254.11\°
