The statement must be true is AC = DF ⇒ A
Step-by-step explanation:
When two triangles are congruent, then
- Their corresponding sides are equal in lengths
- Their corresponding angles are equal in measures
- Their perimeters and areas are equal
∵ ΔABC ≅ DEF
- Their corresponding sides and angles are equal
∴ AB = DE ⇒ AB is the corresponding side of DE
∴ BC = EF ⇒ BC is the corresponding side of EF
∴ AC = DF ⇒ AC is the corresponding side of DF
∴ ∠A ≅ ∠D ⇒ ∠A is the corresponding angle of ∠D
∴ ∠ABC ≅ ∠DEF ⇒ ∠ABC is the corresponding angle of ∠DEF
∴ ∠C ≅ ∠F ⇒ ∠C is the corresponding angle of ∠F
- Look to the answer to find the correct statement
∴ AC = DF
The statement must be true is AC = DF

Answer:
x=5 is in the domain
Step-by-step explanation:
sqrt(x-5) ≥ 0
Square each side
(sqrt(x-5))^2 ≥ 0^2
x-5≥0
x≥5
This is the domain of x
Answer:
84 students
Step-by-step explanation:
Let's suppose that 100% was last year's percentage of students.
100% = 80
1% = 80 ÷ 100 = 0.80
100 + 5 = 105% (This year)
0.80 x 105 = 84
There is another method to this called percentage increase, but I kind of forgot the formula. Hope this method is also correct for the question.
X=1 would be your answer
hope this helps
Remember
(x^m)^n=x^(mn)
and
![x^{m/n}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7Bm%2Fn%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
(m^(2/3))^(1/2)=m^(2/6)=m^(1/3)
m^(1/3)=∛m
last one (rightmost)
