Find the value of x to the nearest tenth. (The last answer is 13.3)
Julli [10]
Your answer is the first option, 8.0. You can find this by using the sine rules for sides, so:
10/sin(90) = x/sin(53)
× sin(53)
7.98 = x
And 7.98 rounded to the nearest tenth is 8.0.
I hope this helps!

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

if y = 25 when x = 6 1/4, then when y = 12, that would mean that we divided 25  by 2.0833. So we can do 6 1/4 divided by 2.0833 is the answer which is 3.00004800077.

Solve the equation.
elena55 [62]

Answer:

C: x=-3 or x=4

Step-by-step explanation:

To solve the equation x^2-x-12=0 we need to factor it

We are looking for two numbers that when multiplied give -12 and when added give -x

This means that when factored, the equation would be (x-4)(x+3)=0

Now we can set each of these equal to 0, which means that at

x=-3 and x=4 , the equation will equal 0
