To get the congruent angles we shall use the sine rule since we have the length of at least 1 side and the values of the angles.
Base length=12 inches
Base angles=50°
Third angle=180-(100)=80°
thus applying the sine rule we shall have:
a/sin A=b/sin B=c/sin C
thus we can get the congruent side as follows:
a/sin 50= 12/sin 80
a=(12 sin 50)/sin 80
a=9.334 inches
since the sides are congruent then the other congruent side will have a length of 9.334 inches
9514 1404 393
Answer:
M = (S -C)/C
Step-by-step explanation:
Starting with ...
S = C + MC
we want to solve for M.
S - C = MC . . . . subtract the term not containing M
(S -C)/C = M . . . . divide by the coefficient of M
Solved for M, the formula is ...
M = (S -C)/C
Calculater I'm pretty sure
what i did to get my answer was 13*6*6 because the whole circle is 12 and so i got 468.
Answer:
Cyrus needs to order 3 full pizzas to feed his 11 friends .
Step-by-step explanation:
The number of friends invited = 11
Share of pizza for each friend = 1/4 pizza
Now, as 1 friend eats 1/4 of a pizza.
⇒ 11 friends eat = 
So, 11 friends can eat 2 .75 pizza.
Since pizza come as a whole number.
And 2. 75 is nearly equal to 3.00
Hence, Cyrus needs to order 3 full pizzas to feed his 11 friends .
