Can someone help me please please please

6.4

Step-by-step explanation:

x/11= tan 30°

x= 11* tan 30°= 11*0.58= 6.4

Option 1 is correct

x = 6.4

Step-by-step explanation:

Notice that since you are dealing with a right angle triangle, you can use the trig function tangent, to solve for "x".

Notice that "x" is the side "opposite" to angle 30 degrees, and the side adjacent to that angle has a 11 units measure.

The tangent function relates this two quantities the following way:

So rounding this answer to one decimal gives: x = 6.4

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
