Find the value of x and y please
valentinak56 [21]

Answer:

x = 20 and y = 14.14213562 ( you can simplify it)

Step-by-step explanation

x = the opposite side divided by sin 45 ( the angle)

    10\sqrt 2 / sin(45)

    20

y = the opposite side divided by the adjacent side

    10\sqrt2 / tan(45)

   14.14213562

    14.14

Find m+n.
Alik [6]
Easy Peasy Lemon Squeezy.

it's difficult because you are looking too hard. think simply. why does it tell you that angle is 40°?

Because if you follow the arrow back to where it starts you will see that exact same angle.

so now you know 1 (not m° or n°) angle inside the triangle is 40° and a complete triangle is 180°.

you also know a straight line has 180° on each side. and the line going from m° to n° splits that in half. meaning there is 90° to the right of it and 90° to the left of it. which means n° must equal 90°.

now you know you have 1 angle inside the triangle with 40° and n°=90° now you just need to find how much m° is.

add 40°+90° then Subtract from 180° to get m°.

180°-130°=50°
m°=50°
