SIN x degrees = 8/10

1 answer:

7 0

$\sin(x) = \frac{8}{10} \\ \alpha = \sin {}^{ - 1} ( \frac{8}{10} ) \\ = 53.13010235$
a (alpha) refers to the angle

you'll still get the same answer if you do
sin^-1 4/5

Help AB and CD are straight lines find z

chubhunter [2.5K]

Answer: z=16

Step-by-step explanation:

Angles on a straight line add up to 180.

As AB is a straight line we can use that to help us find z.

So you would do 68+85+11=164 (I got the 11 from the angle trapped between like C and F as opposite angles are the same).

Then you would do 180-164=16

So z=16

Hope this helps :)
