If angleb is 120 then AC is 120*2 = 240. 360-240 = 120 , 120/2 = 60 . If AB = 60 , angle adb is 30 and angle bdc is 30. DB is 2 * radius because angleA is 90. So with Pisagor AB = 3 , BC = 3 , AD = 3root3 and DC is 3root3.
Answer is = 6+6root3 = 6(1 + root3)
Answer:
i. 5 + 4 = 9
ii. 2 x 3 = 6
iii. 8 - 7 = 1
Step-by-step explanation:
Given: The basic arithmetic operations: addition, subtraction, multiplication or division.
Digits from 1 - 9
Using three arithmetic operations - addition, subtraction, multiplication, and the given digits, the following three expressions can be formed:
i. 5 + 4 = 9
ii. 2 x 3 = 6
iii. 8 - 7 = 1
It can be observed that there is no repetition of digits in the above expressions as required.
Steps to solve:
5(x + 1) = 20
~Distributive property
5x + 5 = 20
~Subtract 5 to both sides
5x + 5 - 5 = 20 - 5
~Simplify
5x = 15
~Divide 5 to both sides
5x/5 = 15/5
~Simplify
x = 3
Best of Luck!
