Answer:
(c)
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° =
= 
Multiply both sides by 12
12 × cos42° = x, hence
x ≈ 8.9 → (c)
Answer:
Option A y-3=2(x-1)
Step-by-step explanation:
we know that
The equation of a line into point slope form is equal to
y-y1=m(x-x1)
In this problem we have
(x1,y1)=(1,3)
m=2
substitute
y-3=2(x-1)
Answer:
m=1
y= 5
Step-by-step explanation:
since y=mx+b
y=1x+5
Answer:
B. 50°
Step-by-step explanation:
∠PLM+ ∠PML =60+70 =130°
So, ∠MPL = 180°-130°=50°
According to the opposite angle theorem,
∠ KPN = ∠MPL which is 50°
