Plzz help <br><br>find value of following : 2sin75°.cos15°

polet [3.4K]

Answer:

$\frac{2+\sqrt{3} }{2}$

Step-by-step explanation:

Using the product to sum formula

sinxcosy = $\frac{1}{2}$ [ sin(x + y) + sin(x - y) ] , then

2sinxcosy = sin(x + y) + sin(x - y)

Given

2sin75°cos15° ← with x = 75 and y = 15 , then

= sin(75 + 15) + sin(75 - 15)

= sin90° + sin60°

= 1 + $\frac{\sqrt{3} }{2}$

= $\frac{2+\sqrt{3} }{2}$

5. Determine the length of side y to the nearest hundredth.

KonstantinChe [14]

Answer:

64.50 cm

Step-by-step explanation:

$\sin \: 51 \degree = \frac{y}{83} \\ \\ 0.7771459615 = \frac{y}{83} \\ \\ y = 0.7771459615 \times 83 \\ \\ y = 64.5031148 \\ \\ \huge \red{ \boxed{ y = 64.50 \: cm}}$

For questions 6 – 10, find the unknown side length. number 10

Sergeu [11.5K]

Answer: $\begin{gathered} s\text{ = 10}\sqrt{2}\text{ \lparen exact answer\rparen} \\ s\text{ = 14.142 \lparen decimal approx.\rparen} \end{gathered}$

Explanation:

10) Given:

hypotenuse = 20

angle = 45°

To find:

length of s

angle = 45

opposite = side opposite the angle = s

To find the value of s, w will apply sine ratio (SOH)

$sin\text{ 45 = }\frac{opposite}{hypotenuse}$ $\begin{gathered} sin\text{ 45 = }\frac{s}{20} \\ s\text{ = 20sin45} \\ sin\text{ 45 = }\frac{\sqrt{2}}{2} \\ \\ s\text{ = 20}\times\frac{\sqrt{2}}{2} \\ s\text{ = 10}\sqrt{2}\text{ \lparen exact answer\rparen} \end{gathered}$ $\begin{gathered} s\text{ = 20sin45} \\ s\text{ = 20\lparen0.7071\rparen} \\ s\text{ = 14.142 \lparen decimal approximation\rparen} \end{gathered}$
