Answer:
B
Step-by-step explanation:
You need to find x, so you'll have to use cos in this case, because x is adjacent to the only angle you have.
So, you'll get:
cos 30 = x/10 (adjacent/hypotenuse)
Rearrange the equation for x:
x = cos 30 x 10
<em>*Since the options you have are in exact values, you can't use a calculator just to find x. </em>
Cos 30 in exact values is √3/2
<em>*you can either memorise these values or learn the trig triangles. either way, just know the exact values for sin, cos and tan for 30, 60 and 90 degrees</em>
So to find x:
x = √3/2 x 10
x = 5√3

Answer:
y = 26/7 or ≈ 3.71
Step-by-step explanation:
3y + 4y= 26
3y + 4y = 7y so,
7y = 26
Divide both side by 7, we got:
y = 26/7 or ≈ 3.71
Hope this helped :3
-6+(-6) it will add up to -12
