2(13+x) less than or equal to 16

Step-by-step explanation:

here you go mate

step 1

2(13+x)≤ 16

step 2

2(13+x)≤ 16  simplify

2x≤-10

step 3

 Divide both sides by (2)

answer

x≤-5

We can find r

Step-by-step explanation:

The law of sine also known as the sine rule, stipulates that the ratio of the length of a side of a triangle and the sine of the angle facing that side is a constant for all the sides of the triangle.

Mathematically, what this means is that;

r/Sin R = q/Sin Q = s/Sin S

Now, for this question, what do we have?

we have angle Q and the side facing it q

We also have angle R.

So the side we can find from here using the sine rule is no other than the side r.

We can find the length of side r from the triangle using the sine rule

And thus we have something like;

9.5/Sine 18 = r/Sine 135
