Step-by-step explanation:
Remark
Triangle BAC is isosceles. It has 2 sides that are both radii of the circle. I assume that C is the center of the circle.
Givens
AC = BC Both of these are radii.
<BCD = 20o Given
<A and <B are equal Both are opposite a radii of the circle
C is the circle's center Assumed otherwise we can't do it.
Solution
<BCD is an exterior angle of Triangle ACB It's on the same straight line as D and A
The sum of 2 remote interior angles = the sum of the exterior angle.
BAC = ABC Stated above
BAC + ABC = 20 Stated right above.
2BAD = 20
BAD = 20/2
BAD = 10
Answer:
C) 61
Step-by-step explanation:
HI okay ....
In the real word 50 cents is equal to .50 ( or in money terms )
How many rides are there ?
19
How much does each ride cost ?
.50
So you need to find how much all the rides would cost together if they were .50 cents each !
To find the answer to this problem you must multiply.
.50 x 19 = ?
The answer to this equation <em>represents the total amount of money he needs </em>
The <u>Minimum</u> in this problem would be the answer as well
.50 x 19 = $9.50
That would be the MINIMUM amount of money Mario need and he would need more money if he went on more rides !
Hope I helped and ask more question for further help :)
Factorize what? I don't see anything to factorize
Do you have a picture of the graphs to choose from? :)
