Answer:
The equation is y = (-4/5)x + 2/5.
Step-by-step explanation:
In a slope form equation, y = mx + b where m represents gradient/slope and b is the y-intercept. Given that the slope is -4/5 so you have to find the value of b by substituing the coordinates into the equation :
The question is an illustration of right-angled triangles
The approximated value of x is 33.5 degrees
The given parameters are:
To determine the measure of angle x, we simply make use of the following sine ratio.
So, we have:
Take arc sine of both sides
This gives
Hence, the approximated value of x is 33.5 degrees
