What is the value of​ x?
olchik [2.2K]

Answer:

x = 4 sqrt(2)

Step-by-step explanation:

This is a right triangle so we can use trig functions

sin theta = opp/ hypotenuse

sin 45 = 4/x

Multiply x to each side

x sin 45 = 4/x *x

x sin 45 = 4

Divide each side by sin 45

x sin 45 / sin 45 = 4 /sin 45

x = 4/ sin 45

We know sin 45 = sqrt(2)/2

x = 4/ sqrt(2) /2

x = 8/ sqrt(2)

We do not leave a sqrt in the denominator so multiply by sqrt(2)/ sqrt(2)

x = 8/ sqrt(2) * sqrt(2)/sqrt(2)

x = 8 * sqrt(2) /2

x = 4 sqrt(2)

Cindy averaged 88 on the first four tests of the year in her Algebra 2 class. If she scores a 95 on each of the remaining tests,
Dvinal [7]
Let x represent the number of remaining tests this year.

[4(88) + x(95)]/(4 + x) = 93
352 + 95x = 372 + 93x
2x = 20
x = 10
