Answer:
measure of angle A is 80 degree.
Step-by-step explanation:
isosceles triangle will have same base angles
first base angle is 50, and the second will also be 50
3 angles of a triangle will add up to be 180 degree.
A is the vertex angle.
So 50 + 50 + A = 180
100 + A = 180
A = 80.
Answer:
I believe b is 5.
Step-by-step explanation:
When you place the points in the values, you get 5=3(0)+b. When you simplify it, you get 5=b. I really hope this is correct, I apologize if it isn't! I hope this helps! :)
Answer:
pi
Step-by-step explanation:
The radius of the circle is 10 units
The circumference of a circle is given by the formula:
C = 2 * pi * r
The diameter of a circle is twice the radius
d= 2r
We want the ratio of the circumference to the diameter
C/d = (2*pi*r)/ 2r
Canceling out the 2 and the r, we are left with pi
C/d = pi
Answer:
Improper
Step-by-step explanation:
in order for it to be proper it must be written as 2
Notice that the two minus signs cancel out, so 12-(-5) is equivalent to 12+5. This sum is clearly 17.
