Mathematics
1 answer:
ss7ja [257]2 years ago
6 0

Answer:

9. 36.87°, 53.13°, 90°

10. 22.62°, 67.38°, 90°

Step-by-step explanation:

9. From the diagram given with the question.

\tan KLJ =\frac{4y}{3y} =\frac{4}{3}

⇒ ∠ KLJ = \tan^{-1} (\frac{4}{3} )= 53.13 Degree.

Similarly, \tan KJL =\frac{3y}{4y} =\frac{3}{4}  

⇒ ∠ KJL = \tan^{-1} (\frac{3}{4} )= 36.87 Degree.

Therefore, the angles of the Δ KJL will be 36.87°, 53.13°, and 90°. (Answer)

10. From the diagram given with the question.

Similarly,  \tan SQR =\frac{5}{12}

⇒ ∠ SQR = \tan^{-1} (\frac{5}{12} )= 22.62 Degree.

Similarly, \tan QSR =\frac{12}{5}

⇒ ∠ QSR = \tan^{-1} (\frac{12}{5} )= 67.38 Degree.

Therefore, the angles of the Δ SRQ will be 22.62°, 67.38°, and 90°. (Answer)

B) Evaluate the algebraic expression 2x2 + 5x +6 if x is equal to (-1).​
Korvikt [17]

Step-by-step explanation:

if x is equal to - 1

Then

2x² + 5x + 6

= 2* ( -1)² + 5 * (- 1) + 6

= 2 - 5 + 6

= 8 - 5

= 3

Hope it will help :)❤

dolphi86 [110]

Answer:

x=9

Step-by-step explanation:

Equation: 5.60x=50.40

Solve: 5.60x=50.40

Divide both sides by 5.60 ( 5.60x/5.60 ) and ( 50.40/5.60 )

x=9

Is the answer 3, 4, 5, or 6? need answer asap please! :)

Don't touch the center. It is already even. 
Start anywhere by connecting a dotted line from one vertex to the next. To keep things so we know what we are talking about, go clockwise. Now you have 2 points that are Eulerized that were not before.

Skip and edge and do the same thing to the next two vertices. Those two become eulerized. Skip an edge and do the last 2.

Let's try to describe this better. Start at any vertex and number them 1 to 6 clockwise.
Join 1 to 2 
Join 3 to 4
Join 5 to 6

I think 3 is the minimum.
