The sum of interior angles of a pentagon is given by:
(n-2)*180
where
n=number of sides
thus the sum of angles in a pentagon will be:
(5-2)*180
=540
hence to evaluate the missing angles we shall proceed as follows:
sum of the given angles is:
63+119+125+116
=423
thus the missing angle, x, will be:
x+423=540
x=540-423
x=117°
Answer:
Translation is 67x-65=x-4, you can use any variable for the number.
Step-by-step explanation:
Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
Answer:
1/3
Step-by-step explanation:
probability= no. of objects/no. of total number
= 3/9
=1/3
Answer:
Triangles ABC and DCB are congruent by SAS
Step-by-step explanation:
Angle CAB is congruent to angle CDB. Side DB is congruent to side AC. Then Ab is congruent to side CD.
