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°
The ratio is 4:7 because since the ratio is red apples to green apples theirs 4 red apples and theirs 7 green
U do 1/3 x 7/1 which then u do 1 x 7 which is 7 then do 3 x 1 which is 3 so it is 7/3
Answer:
-14
Step-by-step explanation:
-19=6k-4k+9
-19=2k+9
subtract 9 from both sides
-28=2k
-14=k
To check your answer plug 14 in for k
