A= 2.5
b= 2
LM/ON= 15
LO/MN= 5
Answer: D) 155
Step-by-step explanation:
let <A, <B,<C are three angles in a triangle.
sum of the three angles in a triangle is 180degree.
<A+<B+<C=180
130+<B+<C=180 since one angle is given
<B+<C =180-130
<B+<C=50
(<B+<C)/2=25----(1)after bisecting sum of the angles
required angle =180-25=155
d is correct answer
Answer:
x=2 y=7
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Answer:
B) 13
Step-by-step explanation:
Average age means to calculate mean:
Mean = (Sum of all numbers)/(Number of numbers)
Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8
Mean = (104)/8
Mean = 13
