Answer: One angle is 52 degrees, and the other is 38 degrees.

Step-by-step explanation:

First, I transcribed the given sentences into equations.

The first sentence says that "Two angles are complementary".

Let's call the first angle x and the second angle y. If two angles are complementary, then their sum is 90 degrees. So we know that x + y = 90.

The second sentence says that "The sum of the measures of the first angle and half the second angle is 64°".

x + y/2 = 64

Then we can use the elimination strategy to solve for one of the variables. In this case, it is easier to subtract the second equation from the first to eliminate x.

  x + y = 90

-  x + y/2 = 64

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

y/2 = 26 ==> y = 52

Now that we know that y = 52, we can substitute that back into the first equation, and get x + 52 = 90, so x = 38.

Answer:

52 degrees = second angle

38 degrees = first angle

Step-by-step explanation:

Complementary angles = they sum to 90 degrees

90 - 64 = 26

since 64 has half of the second angle, we double 26 to get the whole angle amount.

26 * 2 = 52 = second angle

90 - 56 = 38 = first angle

How to convert numbers to scientific notation
Natalka [10]

To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.

2340000 = 2.34 x 10^6

0.000034= 3.4 x 10^-5

Find the slope of the line that passes through the pair of points
BlackZzzverrR [31]

Answer:

undefined

Step-by-step explanation:

To find the slope through 2 points

m = ( y2-y1)/(x2-x1)

   = ( -4 - -3)/(3 - 3)

    = ( -4+3)/(3-3)

    = -1/0

Since it is a number divided by zero, the slope is undefined

You are trying to catch a train, which will be leaving in 2 minutes. There are 2 kilometers between you and the train station. I
noname [10]
K, you have 2 minutes, one minute for one kilometer.
If you're in 60km/h, you're on 1km/m, so, if you cover 1 km in one minute, you need to stay in that speed to get to the train station.
