spin [16.1K]

Answer:

c. 24/25

Step-by-step explanation:

1. Use SOH CAH TOA

2. Highlight C, so you know what your looking for

3. Since were finding the cosine of C we need the side adjacent(next to) and the hypotenuse of C. We know this because of CAH(cosine= adjacent/hypotenuse

4.   C is closest to 24 so we have our adjacent side as 24, this will be the numerator

5. Then find the hypotenuse, which is opposite of the 90 degree angle, marked by the square box in the triangle

6. Our Hypotenuse is 25, which will be our denominator

<h3>7. Giving the answer is 24/25</h3>

What is the abscissa of the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)?
Masteriza [31]

Answer:

Midpoint is (3.5, 2)

Step-by-step explanation:

the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)

To find midpoint of two end points we use formula

(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

(5, 2) , x1 = 5  and y1= 2

(2,2), x2=2  and y2= 2

Plug in all the values and find the midpoint using the formula

(\frac{5+2}{2},\frac{2+2}{2})

(\frac{7}{2},\frac{4}{2})

(3.5, 2)

So midpoint is (3.5,2)
