3 x 3/4= 9/4 or 2 1/4
7 x 3/8= 21/8 or 2 5/8
5 x 2/3= 7/3 or 2 1/3
4 x 1/5= 4/5
Answer: 20
Step-by-step explanation: 6 is halfway so 6 x 2 = 12 then 12x2 is 24 so rounding to the nearest hundred would be 4 is less than five so it becomes a zero and your awnswer is 20! Hope this helps :)
The answer is 45.
Ask me if you still don't understand it because I didn't write any explanation.
As here Angle M(63°) is equal to angle N(63°) that means triangle is isosceles triangle which has its two sides equal to each other. in our case ML = MN
so
3x = x +8
2x= 8
x= 8/2 = 4
so length of MN = x + 8 = 4+8 = 12
so ans is option B
