Answer:
Step-by-step explanation:
Given that:
To evaluate the expression, we must simply substitute the given value of 
, which is 
, for :
Multiply:
Subtract:
-
To check your work, simply set the given expression equal to our solution, :
Add 
to both sides of the equation:
Divide both sides of the equation by the coefficient of , which is 
:
Since it matches the given value of , our solution is correct!
Answer:
85
Step-by-step explanation:
Order of operations rules (PEMDAS) govern here. Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.
Add 2+5 first: 5 + 2*{(7)*5 + 5}
Perform the work shown inside the brackets { and }: 5 + 2*{40}
Perform the indicated mult.: 5 + 80
Finally, add: 85
The answer is the top option.
Answer:
if the "x" is a multiplication symbol, the answer is 2.
Step-by-step explanation:
1. Angle PAB is 90 degrees, as it is formed from the tanget to the circle at A, and the radius drawn to A.
2. AB=BC, because tangents drawn to a circle from the same point are equal.
3. PB is Common, so by the side-side-side congruence postulate, triangles ABP and CBP are congruent.
4. So measure of m(BPA)=x/2 and m(ABP)=73/2.
5.
, x= 107 degrees.
