macy is trying to construct an isosceles triangle. She assigns and angle measurement of 40 degrees to the unique angle of the tr
Hitman42 [59]
Given that Macy wants to construct an isosceles triangle, with the unique angle being 40° it implies that for the triangle to be isosceles, the base angles should be the same. The size of the base angles will be:
(180-40)/2=70
given that that the base is 6 cm, Macy can only form 1 triangle with these dimensions.
The length of the other sides will be found using sine rule
a/sin A=b/sin B
a=6 cm
A=40°
b=?
B=70
hence:
6/sin 40=b/sin 70
b=(6sin 70)/sin40
b=8.77 cm

Guests at a pizza party are seated at three tables. The small table has 5 seats and 2 pizzas. The medium table has 7 seats and 3
bagirrra123 [75]

Answer:

the 5 seated table with the 2 pizzas got more each.

Step-by-step explanation:

\frac{5}{2} = 2\frac{1}{y2} pieces each

\frac{7}{3} = 2\frac{1}{3} pieces each

\frac{12}{5} = 2\frac{2}{5} pieces each

Now change the fractions s that they all have a common denominator.

2\frac{1}{2} = 2\frac{15}{30}

2\frac{1}{3} = 2\frac{10}{30}

2\frac{2}{5} = 2\frac{15}{30}

Thus meaning that the 5 seated table with the 2 pizzas got more each.
