Find the length of the missing side of the triangle below.

qaws [65]

let's call the red triangle R, and the blue triangle B.

big/small

2.5/1.75 = 1.43 (rounded)

1.6/1.12 = 1.43 (rounded)

<u>missing side:</u> 2.35 x 1.43 = 3.36

Solve for x. The triangles in each pair are similar.

pishuonlain [190]

Start off by knowing that the two triangle are congruent. By knowing this you can turn the given numbers into fractions.

9/72 = 7/7x+7

then cross multiply, which equals

63x + 63 = 504

then solve this equation

63x = 441 - subtract 63 from both sides
x = 7 - divide by 63 from both sides

so your answer is x=7

HELP!! I'm not sure what goes in the blank.

Answer:

10 $sin^{2} ($ β $)$

Step-by-step explanation:

We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10 $sin^{2} ($ β $)$ on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10 $sin^{2} ($ β $)$ .

You can also use double angle formulas from the previous step:

(sin(2β) = 2 sin(β) cos(β))and find that:

5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =

10 $sin^{2} ($ β $)$ cos(β)

But since cos(β) is already present, we can see that the answer is 10 $sin^{2} ($ β $)$
