PLEASE HELP ME ILL MAKE BRAINLIEST!!!!! <br> I need the correct answer

Answer:

Step-by-step explanation:

Hello There!

<u>Trigonometric Ratios</u>

sin = opposite divided by hypotenuse

cos = adjacent divided by hypotenuse

tan = opposite divided by adjacent

we need to find x and we are given its opposite side length and the hypotenuse

so the trigonometric ratio we need to use is sin

knowing that sin = opposite side divided by hypotenuse we create an equation

$sin(x)=\frac{51}{61}\\\frac{51}{61} = .8360655738\\arcsin(sinX)=x\\arcsin(.8360655738)=56.72695659$

our final step is to round to the nearest tenth of a degree

so we can conclude that the measure of angle A is 56.7

note: arcsin = inverse of sin

10<br> Using the quadratic formula to solve x2 = 5 – X, what are the values of x?

loris [4]

x^2 = 5 - x

x^2 + x - 5 = 0

-1 +/- $\frac{ \sqrt{ {1}^{2} - 4(1 \times - 5) } }{2}$

x = (1 + √21) / 2

x = (1 - √21) / 2

For the rectangle shown, which equation can be used to find the value of x?

trasher [3.6K]

Answer:

Pythagorean theorem $a^{2} +b^{2} =c^{2}$

Step-by-step explanation:

$a^{2} +b^{2} =c^{2} \\x^{2} +3.6^{2} =7.4^{2} \\x^{2} +12.96=54.76\\x^{2} =\sqrt{41.8} \\x=6.47\\$
