Answer:
a. $435
b. 33.33%
Step-by-step explanation:
P.S - The exact question is -
Let Clara raised money = x
As given,
Ali raised 20% more than Clara
⇒Ali raised money = 
Also given,
Clara raised 
times more than Shan
Clara raised money = Shan raise money + times shan raired money
⇒Clara raised money = 
Shan raised money
⇒Shan raised money = 
times Clara
⇒Shan raised money = x
As given,
Ali raised $58 more than shan
⇒
⇒
⇒
⇒x = (29)(5) = $145
∴ we get
Clara raised money = x = $145
Ali raised money = 
= $174
Shan raised money = x = $116
a.)
Total raised money = $145 + 174 + 116 = $435
b.)
Percentage of money Clara raised = 
×100% = 
×100% = 33.33%
Answer:
The amplitude is 3.
Step-by-step explanation:
They are sim because there just are short bud I don’t know
Sorry, it's late, and I'm a bad explainer.
The error is adding (2x-12) with x and 30. This is wrong because you are adding the angles inside the triangle and you are assuming that (2x - 12) is the unlabeled angle INSIDE the triangle, when it is the exterior angle/outside of the triangle.
A straight line is also 180°.
(2x - 12) + ? = 180
30 + x + ? = 180
If you look at the equations, and put parentheses around 30 + x, (30 + x) and (2x - 12) should be the SAME NUMBER. So you could set them equal to each other to find x. (or you could also look at the picture and see that they both need/are missing the same angle)
2x - 12 = 30 + x
x = 42
Now you plug 42 into the exterior angle equation
2(42) - 12 = 84 - 12 = 72°
