A and a' are vertical angles, therefore a' = a

We know: The sum of the measures of triangle is always 180°.

Therefore: a' + b + d = 180° → d = 180° - a - b.

d and c are adjacent angles, therefore d + c = 180°

substitute

180° - a - b+ c = 180°    |-180°
-a - b + c = 0    |+a  |+b
c = a + b

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>

Which equation can be used to find the number of fish in the pond on June 1?
olga_2 [115]

Answer: The required equation is f-52=63 and the number of fishes in the pond on June 1 = 115


Step-by-step explanation:

Given: The number of fishes in pond on July 1 = 63

Also, it is said that the number of fishes in pond on July 1 is 52 fewer(lesser) than the number of fishes in pond on June 1.

Let f be the number of fishes in pounds on June 1.

then the required equation will be

f-52=63

Now, add 52 on both the sides  of the equation, we get

f=63+52\\\Rightarrow\ f=115
