Answer:
5/6
Step-by-step explanation:
Slope equals y 2 minus y 1 divided by x 2 minus x1
1-(-4)/4-(-2)
5/6
Answer:
.
Reference angle is 
Step-by-step explanation:
Given the value of x. we have to find the correct value of cosx.
Now, we have to find the exact value of 
Now, we have to find the reference angle of .
Since the angle lies in second quadrant, the reference angle formula is
Reference angle= 
.
=
Answer:
64.87° = 65°{ to the nearest degree}
Step-by-step explanation:
From the figure Catherine is standing 105m from the point B where the Ballon is; this description fits a= 105 m from the diagram.
Similarly Aisha is standing 95m from the point B where the Ballon is; this description fits c= 95 m from the diagram
A = ? ( The angle of elevation of Aisha towards the balloon)
C = 55°
From Sine rule
It states that the sine of an angle divided by its corresponding side is equal for all corresponding angles and sides along the triangle.
This is expressed mathematically as;
Sin A/ a= SinB/ b= SinC/c
We take the pairs of relevance;
Sin A/ a = SinC/c
There SinA = SinC/c × a
=Sin55/95 × 105
= 0.9053
A = Sin^(-1)[0.9053]
A = 64.87° = 65°{ to the nearest degree}
Answer:
c
