Answer:
1.77 x 10^6
Step-by-step explanation:
2,200,000-430,000
1,770,000
Answer:
23 sides
Step-by-step explanation:
The sum S of the interior angles of an n sided polygon is given as
S = (n - 2)180°
Where S is the sum of the interior angles and n is the number of sides.
Given that the sum of the interior angles is 3780° then
3780° = (n - 2)180
Divide both sides of the equation by 180
21 = n - 2
n = 21 + 2
= 23
The polygon has 23 sides
Answer:
x = 7
Step-by-step explanation:
Let x = the number. Then
"Triple a number" means 3x
"is the same as" means =
"double the number increased by 5" means 2x + 7
∴ 3x = 2x + 7
Subtract 2x from each side
x = 7
The answer is x = 7.
Check:
3 × 7 = 2 × 7 + 7
21 = 14 + 7
21 = 21
OK.
Answer:
Angle measurements of 35°, 35°, and 110°
Angle measurements of 40°, 60°, and 80°
Step-by-step explanation:
If you specify only the three angles, you can have an infinite number of similar triangles of different sizes.
A is wrong. There can be only one triangle in which all three side lengths are specified.
C is wrong. The angles do not add up to 180°.
