Try this option (see the attached picture):
1. to determine an equation of line y₁, which ⊥y and includes point a(0;5);
2. to calculate intersection point of y and y₁ (point B);
3. to calculate distance between the point A and B, using vectors properties.
Answer:
115
Step-by-step explanation:
180-65=115
the whole triangle is 180 degrees so subtract 65 degrees from it
Answer:
5
Step-by-step explanation:
To solve the equation you'll use the distance formula:
Substitute the equation with (0,0) being 
,
and (-4,-3) 
if you solve this you'll get 5
