Subtract. Write your answer in simplest form.

7/10 - 3/10

4/10 or 2/5 or if you want, 0.4

Step-by-step explanation:

They both are tenths so, all you have to do is subtract 7-3. 7-3 is 4 so, the answer would be 4/10. 4/10 simplified is 2/5. I hope this helped.

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
