Step-by-step explanation:

∫ dt / (cos²(t) ⁹√(1 + tan(t)))

If u = 1 + tan(t), then du = sec²(t) dt.

∫ du / ⁹√u

∫ u^(-1/9) du

9/8 u^(8/9) + C

9/8 (1 + tan(t))^(8/9) + C

LekaFEV [45]

Answer:

i) not similar but corresponding angles have equal measures.

  the blue object required to be dragged to the box is the fourth object which is a square. A square will not have proportional lengths and is not similar to the given figure but the corresponding angles will have equal measures.

ii) not similar but side lengths are proportional.

the blue object required to be dragged to the box is the first object which is a parallelogram. A parallelogram will have proportional lengths and is not similar to the given figure because the corresponding angles do not have equal measures.

Find the value of x<br> A. 8 <br> B. 4<br> C. 19<br> D. 24
hodyreva [135]
<h3>Hello There!!</h3>

Given figure is a <u>parallelogram</u>

<u>To </u><u>Find</u>

Value of"x"

<h3><u>Solution</u></h3>

m \angle \: A = m \angle  \: C

2x + 35 = 5x - 22

\implies 2x - 5x =  - 22 - 35 \div  \\  \implies - 3x =  - 57 \\   \\ \implies x =  \frac{ - 57}{ - 3}  \\  \\  \implies  x =  \cancel\frac{ - 57}{ - 3} \\  \\  \implies x = 19

\therefore \text{Option C= 19 is the correct answer}

<h3>Hope this helps</h3>
