Answer:
2/x + 3/y = 5
Step-by-step explanation:
A linear equation refers to any equation that can be written in the form;
ax+b=0 or y - mx -c = 0
The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).
All the equations given are linear, except the last equation;
2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;
Answer:
Step-by-step explanation:
First, we calculate the unknown angle of the left triangle and right triangle:
Unknown angle for left triangle⬆️
Unknown angle for right triangle⬆️
Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:
The angle 65° and angle of x are vertical angle.(both are equal)
So... <u>x= 65°</u>
