Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°
B = 18 because 67 - 49 = -18
-18 =-b
Divide by negative 1 because you can't have a negative variable in your answer.
Answer:
Option A is the answer.
Step-by-step explanation:
We have been given the ordered pairs.
The function is a representation
For a mapping to be a function there should always be a unique value of y for different values of x.
So the mapping :
(-4,-2) (-1,3) (0,3) (5,-6)
3 has two different values hence not a function.
Therefore, Option A is the answer.
Step-by-step explanation:
7(x-2)+3 (x+2)=5 (x-6)
- 7x-14+3x+6=5x-30
- 10x-8=5x-30
- 10x-5x=-30+8
- 5x=-22
- x=-22/5
