Pedro simplified four over seven ÷ five over eight.; his work is shown below. Identify where he made his error. Original division problem: four over seven ÷ five over eight. Step 1: our over seven multiplied by eight over five. Step 2: four times five over seven times eight. Step 3: wenty over fifty-six. Step 4: five over fourteen.

the answer is 8/21

hope this

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
