Use the Pythagorean theorem to find the distance between (-5,2) and (10,10)​

D^2 = (x2-x1)^2 + (y2-y1)^2

D =sqrt((10+5)^2 + (10-2)^2)

D P SQRT(15^2 + 8^2)

D = sqrt(225 +64)

D= sqrt(289)

D = 17

The distance is 17

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.

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
