Option ( A ) is the correct answer.
- Sum of all interior angle of a regular pentagon is 540°
- Number of edges in regular pentagon is 5.
- Number of vertices in regular pentagon is 5.
Answer:
the answer is d the person above is wrong.
Step-by-step explanation of the wrong answers: b is wrong because it will be 3,3,3,3,3,3,3,4,4,4,5,5,5,6,6. A is wrong because 3 isn't in the middle. C is wrong because then 6-2 is 4. There's your explanation.
Answer:
-23.3
Step-by-step explanation:
Given:
a = 3, b = -2, c = 5. 1
Equation;
2a + 3b - 3c + 4b
Find:
Solution
Computation:
2a + 3b - 3c + 4b
2(3) + 3(-2) - 3(5.1) + 4(-2)
6 - 6 - 15.3 - 8
-23.3
Answer:
x = 10
m<A = 132 degrees
m<B = 48 degrees
Step-by-step explanation:
Supplementary = angles that make up 180 degrees
We know <A and <B are supplemntary, so 2x+28+6x+72 = 180.
8x + 100 = 180
8x = 80
x = 10
I input 10 into the equations to solve for the measures of the angles
