Question

A rectangular piece of card is cut in a straight line along its diagonal, as shown below. Work out the size of angle y. Give your answer in degrees to 1 d.p. Y 52.2 cm % 29.4 cm Not drawn accurately​

Answer 1

Answer:52.3

Step-by-step explanation:Joking

Answer 2

the tangent of angle y is equal to the length of the side opposite the angle y divided by the length of the side adjacent to the angle , so tan y = 52.2/29.4=1.77551....

if you wish to calculate the measure of the angle whose tangent is 1, type 2nd tan 1.77551 and the calculator displays: 60.610985...=60.6°.

y≈60.6°

i'm french to calculate i have a casio but with any brand you find the same measure measures are always approximate
