Answer:
Step-by-step explanation:
<h3>Question </h3>
- It is given the ∆ABC≅∆FDE and AB=4 cm, ∠B=40⁰ and ∠E=60⁰, then which of the following is true.
- (A) DE=4cm, ∠A=80⁰
- (B) DE=4 cm, ∠C=80⁰
- (C) DF=4 cm, ∠A=80⁰
- (D) DF=4cm, ∠C=80⁰
<h3>Solution</h3>
<u>Corresponding sides and angles are:</u>
- AB ≅ FD
- ∠A≅∠F, ∠B≅∠D, ∠C≅∠E
<u>Given</u>:
- AB = 4 cm, so FD = 4 cm
- ∠B = 40⁰ and ∠E = 60⁰, so ∠D = 40⁰ and ∠C = 60⁰
and
- ∠A = ∠F = 180⁰ - (40⁰ + 60⁰) = 80⁰
Considering all above we see that correct answer option is (C)
Answer: 864 square inches (choice A)
Work Shown:
area = length*width
area = 36*24
area = 864
Answer:
median = 17.5
Step-by-step explanation:
The median is the middle value of a data set arranged in ascending order. If there is not a middle value then the median is the average value of the numbers either side of the middle.
Data in ascending order is
8, 15, 17, 18, 19, 21
The median is between 17 and 18, hence
median = 
= 17.5
Answer Yes it is a fair game
