1. Identify the pair of fractions equivalent to 25/45 *
stepladder [879]

Answer:

Hope this helps! Brainliest please

Step-by-step explanation:

1. Divide both by 5, so the correct answer would be 5/9, and then multiply both by 3, so the correct answer would be 75/135. The answer is 5/9,75/135

2. 4 and 2/7 because 7 *4=28. That leaves 2 sevenths over.

3. Divide both by 9. Your answer is 3/4

Answer:

FC=25.9

Step-by-step explanation:

<u>Congruent Triangles</u>

The figure shows two triangles FCD and FED. One of their sides is the radius of the circle, they both form a 90° angle with the line CD and ED and they share the same segment FD.

Thus, both triangles are congruent and we have the length of a side (12 units), one common side (the hypotenuse) and one unknown leg that must be equal. Therefore

13x-16=4x+11

Solving

9x=27

x=3

The required side FD is the hypotenuse of any of the triangles. The unknown leg can be calculated by

13x-16=23

Or

4x+11=23

Thus

FD^2=12^2+23^2=673

Solving

FD=\sqrt{673}

\boxed{FC=25.9}

(cos A + cos b)^2 + (sin A + sin B)^2=?
emmasim [6.3K]
First, we expand the equation:

cos^{2}A+2cosAcosB+ cos^{2}B+sin^{2}A+2sinAsinB+sin^{2}B

Then, we combine certain terms in order to simplify them using trigonometry identities.

cos^{2}A+sin^{2}A+cos^{2}B+sin^{2}B+2cosAcosB+2sinAsinB

Note these identities:
Pythagoran relation: cos^{2}A+sin^{2}A = cos^{2}B+sin^{2}B=1
Sum and Difference Formula/Identities: cos(A-B) = cosAcosB+sinAsinB

Thus, if we apply these identities, the simplified equation would be:
2(cos(A-B))+2

Simplying further, the answer would be

2[cos(A-B)+1]
