Because Angle A and B are supplementary they will ad up to 180 degrees.
the measure of angle A is 101 degrees
Answer:
Step-by-step explanation:
The area of a triangle is:
A=05*b*h
b= base = x
h = height = x-12
A = (1/2)(x)(x-12)
Answer:
B
Step-by-step explanation:
r^2 is 0.9997, and after 10 years it'll be 95660

This can be considered as a very easy Question where you have to find the value of √85 and √86 upto 2 decimal places then we could find it easily.
Let's start!
Value of √85=9.21
Value of √86=9.27
Now it is obvious that 9.25 lies between √85 and √86.

What are rational no.?
Any pair of numbers which is in the form of p/q where p and q are integers and p and q are co-prime is called rational number.
Answer:
2x-10+x+x+10=180, or 4x=180
Step-by-step explanation:
So since the total is 180, you add them all up like an equation.
So,
2x-10+x+x+10
Combine like terms
4x=180
x=45
Then plug it back in to the equations.
x=45
(2x-10)=80
(x+10)=55
