Answer:

A = 41.4°

Step-by-step explanation:

Reference angle = A

Length of Adjacent side = 6

Length of Hypotenuse = 8

Apply the trigonometric function, CAH.

Cos A = Adj/Hyp

Substitute

Cos(A) = \frac{6}{8}

A = Cos^{-1}(\frac{6}{8})

A = 41.4° (approximated to the nearest tenth)

Find the solution to the system of linear equations y = 5x + 4 and y = −3x + 12 using the intersection method. Check your answer
Umnica [9.8K]

Answer:

The solution to the system of linear equations is (1,9).

Step-by-step explanation:

The given system of linear equations

y=5x+4            ... (1)

y=-3x+12           .... (2)

Subtract equation (2) from equation (1) to eliminate y.

y-y=(5x+4)-(-3x+12)

0=5x+4+3x-12

On combining like terms, we get

0=(5x+3x)+(4-12)

0=8x-8

Add 8 on both sides.

0+8=8x-8+8

8=8x

Divide both sides by 8.

1=x

The value of x is 1.

Substitute x=1 in equation (1).

y=5(1)+4

y=5+4

y=9

The value of y is 9.

Therefore the solution to the system of linear equations is (1,9).
