Answer:
m∠1 = 110° and m∠2 = 70°
Step-by-step explanation:
m∠1 = 110° since vertical angles
To find m∠2, m∠1 and m∠2 must add to 180°
m∠1 + m∠2 = 180°
110° + m∠2 = 180°
m∠2 = 70°
9514 1404 393
Answer:
- (2x-10) +x +(x+10) = 180
- x = 45
- (2x-10)° = 80°
- (x+10)° = 55°
- x° = 45°
Step-by-step explanation:
The equation is an expression of the fact that <em>the sum of the angles in a triangle is 180°.</em>
(2x -10)° +x° +(x +10)° = 180°
For the purposes of the answer box, I'd leave off the degree symbol:
(2x -10) +x +(x +10) = 180
__
This simplifies to ...
4x = 180
x = 45
Then the angles (CW from top) are ...
(2·45 -10) = 80°
(45 +10)° = 55°
(45)° = 45°
Let the final score of White Sox = x
the final score of Marlins = y
White Sox won by 2 runs. Thus
x = y +2
White Sox had twice as many runs as Marlins
x = 2y
From the equations,
2y = y + 2
=> 2y - y = 2
=> y = 2
x = 2y = 2×2 = 4
Hence, final score of
White Sox = 4
Marlins = 2
Also 114 as they are corresponding angles
Answer:
B
Step-by-step explanation:
Open dots represent everything leading up to a number, but do not include the number itself, and closed dots include the number. Therefore, it would need to be B.
