Answer:
<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between, we can calculate for ∠A using the sine law:
</em>
<em>
</em>
<em>b / sin B = a / sin A
</em>
<em>
</em>
<em>2.45 / sin 60 = 2 / sin A
</em>
<em>
</em>
<em>sin A = 0.707
</em>
<em>
</em>
<em>A = 45˚
</em>
<em>
</em>
<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>
Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
