Answer:

x = 10

Step-by-step explanation:

perimeter is the sum of all sides

2 sides = 'x+5' cm

2 sides = 'x' cm

2(x + 5) + 2x = 50

2x + 10 + 2x = 50

4x + 10 = 50

4x = 40

x = 10

Answer:x=10

Step-by-step explanation:

First let's create an equation:

2(x+5)+2x=50

2x+10+2x=50

4x+10=50

4x=40

x=10

If f(x) = x + 6, g(x) = 3x and h(x) = 10/x , find the value of f^-1(g(h(5))).
NNADVOKAT [17]
Start from inside to the out side of the function;
h(5)=10/5=2
g(h)=g(2)=3*2=6
now, get the f inverse of x;
f(x)=y=x+6
x=y-6
replace x with y and y with x
y=x-6
so f^-1= x-6
so f^-1(g)=f^-1(6)=6-6=0
I am not sure only of the last value, but pretty sure of the rest.

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°
