Serious answers only please !! 20 points as well as brainliest for correct answer!!
Gre4nikov [31]

Answer:

Measure of angle A = 55°.

Step-by-step explanation:

From the picture attached,

\frac{AC}{LN}=\frac{BC}{LM}

\frac{10}{5}=\frac{8}{4}

2 = 2

Corresponding sides of the given triangles ΔACB and ΔNLM are proportional.

Therefore, ΔACB ~ ΔNLM.

m∠A = 180° - (90° + 35°) [By triangle sum theorem]

         = 180° - 125°

         = 55°

Measure of angle A is 55°.

9 to the power 18 = 27 to the power x work out the value of x
Strike441 [17]

Answer:

Step-by-step explanation:

27^x = 9÷(3^x)

So (3^3)^x = (3^2)÷(3^x)

So 3^3x = 3^(2-x)

Comparing powers on both sides,

3x = 2 - x

So, 4x = 2

So, x = 1/2

Given ( 27 ) ^ x = 9 / 3 ^x

⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x

⇒ ( 3 ³ )^x = 3² / 3^x

⇒  3 ^ 3x × 3^x = 3²            [ since  ( a ^m)^n = a ^mn ]

⇒ 3^ (3x +x) = 3²                [ since a^m × a^n = a ^m+n ]

⇒ 3^4x = 3²

⇒4x = 2                      [ since  If a ^m = a ^n then m = n ]

⇒ x = 2 / 4

 ∴ x = 1 / 2

I hope this helps you.

Solve the system.<br> 2x+y = 3<br> -2y = 14 - 6x
bezimeni [28]

Answer:

The solution is: (2, -1)

Step-by-step explanation:

First we rewrite the second system equation

-2y = 14 - 6x   →   6x-2y=14

Now we have the following system of equations:

2x+y = 3

6x-2y=14

To solve the system multiply the first equation by -3 and add it to the second equation

-6x+-3y = -9

6x-2y=14

--------------------------------------

0-5y=5

y=-1

Now we substitute the value of y in the first equation and solve for x

2x-1 = 3

2x= 4

x= 2

The solution is: (2, -1)
