I will give brainliest thanks

vampirchik [111]

Answer: Correct answer is 1st option , 12.3

Step-by-step explanation:

We can find the value of x by calculating the tangent of the angle 39.

We know, that tangent of an angle in a triangle = Perpendicular/Base, corresponding to that angle.

So, tan 39 = 10/x

Again, we know that tan 39 = .81

So, .81 = 10/ x

or, x = 10/.81

or, x = 12.34

So value of x to the nearest tenth = 12.3

Hope thsi helps

Thank you

Find the exact value using a sum or difference identity of cos 105°

mixas84 [53]

Answer:

Step-by-step explanation:

We can easily determine the exact value of this unknown angle by breaking it into known angles that can add together to give up 105. For example, 105 degrees is 60 + 45, both of which are found on the unit circle. We ill also use the trig identity for the sum of the cos of 2 angles which is:

$cos(60+45)=cos60cos45-sin60sin45$

These values are found on the units circle, so make sure you have one handy. Those values fill in as follows:

$(\frac{1}{2})(\frac{\sqrt{2} }{2})-(\frac{\sqrt{3} }{2})(\frac{\sqrt{2} }{2})$ which simplifies to

$\frac{\sqrt{2}-\sqrt{6} }{4}$

Higher Order Thinking On Friday,

oksian1 [2.3K]

Answer:

The Total number of peoples went to street fair including all three days is 785 peoples .

Step-by-step explanation:

Given as :

The number of people went to fair on Friday = F = 215 peoples

The number of people went to fair on Saturday = Sa = 163 more people than on Friday

So, The number of people went to fair on Saturday = The number of people went to fair on Friday + 163 peoples

∴, The number of people went to fair on Saturday = 215 + 163 = 378 peoples

And

The number of people went to fair on Sunday = Su = 192 peoples

So , The Total number of peoples went to fair = The number of people went to fair on Friday + The number of people went to fair on Saturday + The number of people went to fair on Sunday

So, The Total number of peoples went to fair = 215 peoples + 378 peoples + 192 peoples

∴ The Total number of peoples went to fair = 785 peoples

Hence , The Total number of peoples went to street fair including all three days is 785 peoples . Answer
