Hey there! I'm happy to help!
We have 110 minus a certain percent of 110 equals 88. Let's call this percent p and solve.
110-110p=88
We subtract 110 from both sides.
-110p=-22
We divide both sides by 110.
p=0.2
Therefore, the percent decrease is C) 20%.
Have a wonderful day! :D
Answer:
x = 125°
Step-by-step explanation:
The sum of the angles around a point = 360° , then
90 + 145 + x = 360°
235° + x = 360° ( subtract 235° from both sides )
x = 125°
Answer:
1 2/8
Step-by-step explanation:
3/8 + 3/8 + 3/8 + 3/8= 12/8 = 1 4/8 or 1 1/2
Answer:
The answer is below
Step-by-step explanation:
The complete question is given in the image attached below
m∠1 + m∠2 = 180° (sum of angles on a straight line)
m∠1 + 98 = 180
m∠1 = 180 - 98
m∠1 = 82°
m∠2 + m∠3 + m∠7 = 180° (sum of angles in a triangle)
98 + 23 + m∠7 = 180
m∠7 + 121 = 180
m∠7 = 180 - 121
m∠7 = 59°
m∠4 = m∠7 (alternate angles)
m∠4 = 59°
m∠6 + m∠7 + m∠8 = 180° (sum of angles on a straight line)
m∠6 + 59 + 70 = 180
m∠6 + 129 = 180
m∠6 = 180 - 129
m∠6 = 51°
m∠4 + m∠8 + m∠9 = 180° (sum of angles in a triangle)
59 + 70 + m∠9 = 180
m∠9 + 129 = 180
m∠9 = 180 - 129
m∠9 = 51°
m∠4 + m∠5 = 180° (sum of angles on a straight line)
m∠5 + 59 = 180
m∠5 = 180 - 59
m∠5 = 121°
m∠10 + m∠9 = 180° (sum of angles on a straight line)
m∠10 + 51 = 180
m∠10 = 180 - 51
m∠10 = 129°
