Answer:

58.4

119.2

Step-by-step explanation:

Givens

Let one angle = x

Let the other angle = x + 58.4

Together they make 180 degrees.

Equation

x + x + 58.4 = 180 Collect like terms.

Solution

2x + 58.4 = 180 Subtract 58.4 from both sides

2x = 180 - 58.4

2x = 121.6 Divide by 2

x = 60.8

Answer

x = 60.8

x + 58.4 = 119.2

Answer:

Step-by-step explanation:

α - smaller angle

β = α + 58,4° - larger angle

The sum of supplementary angles is 180°.

Therefore:

α + β = 180°

α + α + 58.4° = 180°

2α = 180° - 58.4°

2α = 121.6°

α = 121.6°÷2 = 60.8°

β = 60.8° + 58.4° = 119.2°

Checking: 119.2° + 60.8° = 180°

Firlakuza [10]

Answer:

$= log_{10}(\frac{6\sqrt{2} }{\sqrt{7} } )$

Step-by-step explanation:

Given the expression $log10\sqrt{36} + log10\sqrt{2} - log10\sqrt{7} \\$

According to the law of logarithm;

loga + log b = log(ab) and log a - log b = log(a/b)

The given expression becomes;

$log10\sqrt{36} + log10\sqrt{2} - log10\sqrt{7} \\= log_{10}(\frac{\sqrt{36} \times \sqrt{2} }{\sqrt{7} })\\= log_{10}(\frac{6\sqrt{2} }{\sqrt{7} } )$

A line passes through the points (2,-2) and (-6,2). The point (a.-4) is also on the line. What is the value of a?

Zigmanuir [339]

Answer:

Step-by-step explanation:

Hey there) The formula of your line is:

$-2=2k+b\\2=-6k+b\\=>4=-8k\\k=-0.5\\=> b=-2+1=-1\\=>y=-\dfrac{1}{2}x-1\\$

If point has y=-4, then:

$-4=-\dfrac{1}{2}a-1\\4=\dfrac{1}{2}a+1\\a=6$

Hope this helps) Have a nice day/night :)

Which of the following statements best describes the graph of -5x+2y=1

ahrayia [7]

The answer is the third option.
x and y are both to the first degree so we know it makes a straight line.
Next check the ordered pairs to see which set are true in the equation.
