Length of the side of the equilateral triangle is 4cm
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
Answer:
option C is correct.
Step-by-step explanation:
Answer:
The notation "f(x)" is exactly the same thing as "y"
Step-by-step explanation:
The effect of using f(x) instead of y is that it allows us to talk about f.
If we have an equation relating X to Y then that's a relationship between rwo nimbers.
For example if you have that y=
...then that means that X and Y are some numbers obeying that equation
The number of people who like to fish AND swim is 8 people
The number of people who ONLY like to fish is 11 people
The number of people who ONLY like to swim is 23 people
The number of people who DO NOT like to fish is 23 people
The number of people who DO NOT like to swim is 11 people
The number of people who DO NOT like EITHER to fish or to swim is 6 people
The total of people is 11+8+23+6=48
