Answer:

8

Step-by-step explanation:

sin theta = opposite side/ hypotenuse

sin 30 = 4/x

Multiply each side by x

x sin 30 = 4

Divide each side by sin 30

x sin 30 /sin 30 = 4 sin 30

x = 4 /sin 30

We know that sin 30 = 1/2

x = 4 / 1/2

x = 8

For this case we have to, by trigonometric properties applied to rectangular triangles:

Sine (30) = \frac {Cathet \ opposite} {Hypotenuse}\\Sine (30) = \frac {4} {x}

Clearing x:

x = \frac {4} {Sine (30)}\\x = \frac {4} {\frac {1} {2}}\\x = 8

Thus, the value of the hypotenuse is 8.

Answer:

x = 8

Simplify the expression 9t^2+14-17t+6t-8t^2
slamgirl [31]

Answer:

t^2 - 11t + 14

Step-by-step explanation:

Begin by grouping like terms in 9t^2+14-17t+6t-8t^2.

First we have 9t^2 - 8t^2, or 1t^2.

Next, we have -17t + 6t, or -11t.

Last, we have the constant term 14.

The expression in simplified form is t^2 - 11t + 14.
