Answer:
15cm
Step-by-step explanation:
Let x be the arc circumference.
The circumference of a circle usually subtends to 360°, that is, one complete revolution is 360°.
#Given the arc angle as 45° and the circumference as 120cm, the arc circumference can be obtained as:
#Apply proportions to find x:
Hence, the arc circumference is 15cm
You know the long leg<span> (the </span>side<span> across from the </span>60<span>-degree angle). Divide this </span>side<span> by the square root of 3 to </span>find<span> the short </span>side<span>. Double that figure to </span>find<span> the hypotenuse. </span>Finding<span> the other </span>sides<span> of a </span>30-60-90 triangle<span> when you know the hypotenuse.</span>
the slope is -4, so B is the answer.
I will give you 2 points.
y+1=1/3(x-3)
y+1=1/3x-1
y=1/3x-2
If x=0:
y=0-2
y=-2
(0,-2)
If x=3
y=3*1/3-2
y=1-2
y=-1
(3,-1)
If 5y-10=0 it would equal 2. Add ten to both sides and then divide 5 to both sides which leaves you with y=2
