Answer:

  • 52°

Step-by-step explanation:

We know that sine and cosine are equal when angles are complementary.

  • sin 38° = cos m
  • sin 38° = cos (90° - 38°) = cos 52°
  • cos m = cos 52°
  • m = 52°

HELP MEE IM DIEING please i need help I'm very stupid and idk these things and if u could explain to me how I can add fractions
Dafna1 [17]
Fraction adding: Okay, so if you have two fractions with the same denominator like 2/3 and 1/3 then they are easily added. Just add the numerators together and then keep the denominator. Like this: 2/3 + 1/3 = 3/3 or 1 whole. Here is something for fractions with unlike denominators.

A line has gradient 5.
MAVERICK [17]

Answer:

x = k - 3

Step-by-step explanation:

Given parameters:

  Gradient of the line = 5;

Coordinates; M(x, 8)

                       N(k, 23)

Solution:

If we use the expression for finding the slope of the line, we can solve this problem;

     Slope  = \frac{y_{2} - y_{1}  }{x_{2} - x_{1} }

    where

    x₁ = x    y₁ = 8

    x₂ = k    y₂ = 23

Input the parameters:

       5  = \frac{23 - 8}{k -x }

          15 = 5(k - x)

           3= k- x

           k - x = 3

 Express x in terms of k;

          -x = 3 - k

Multiply through by -1;

          x = -3 + k

          x = k - 3

The owner of a sporting goods store in Phoenix, Arizona surveys her customers to determine the proportion of customers that play
BabaBlast [244]

Answer:

C

Step-by-step explanation:

This is a sample proportion where p^ represents the sample proportion.

If we have p^ = 0.6, it means about 60% of the sample are in agreement with or significant to the case study.

The case study here is 'customers that play racquetball' and p^ was 0.16.

This means that 16% of the customers of the sample said they play racquetball.
