Answer:
first one
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
g^2 =81
so, g=9
g-2=9-2=7
A graphing calculator is a great help for problems of this nature.
x ∈ {-5.63, -0.55, 2.59}
C is greater than or equal to $40 (which means put the > sign with a line under it).
Answer:
40 degrees
Step-by-step explanation:
The sum of the angles is 180.
A 100 degree angle cannot be a base angle because then
the sum of the base angles would be 200 degrees.
The 100 must be the vertex angle.
Equation:
x + x + 100 = 180
2x = 80
x = 40 degrees.
Each of the base angles is 40 degrees.
