Answer:
The answer is option B. 240
Answer:
Step-by-step explanation:
Given
The attached triangle
Solving (a) BA
Considering the tangent of angle C, we have:
This gives:
Make BA the subject
--- approximated
Solving (a) BC
Using Pythagoras theorem
Square root of both sides
Answer:
there are no real solutions
Step-by-step explanation:
there is a rule that says
so we have
and we have the definition
so we have
and using the quadratic formula we get that
there are no real solutions
slope = y2-y1 / x2-x1=
-1 -5 / 2 - -1 = -6/3 = -2
slope = -2
y intercept = y =mx +b
y = -2x +b
y=-2*-1 +b
5 = -2 +b
b = 5-2
b =3
y intercept = 3
