Answer:
Part a): 100 degrees
Part b): Isosceles Triangle
Step-by-step explanation:
Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.
180 - 80 = 100
Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.

she has 2/3 of it done in an 1/3 of an then in an hour 6/3 will be done and 6/3 simplified is 2
Answer:
1 and 2
Step-by-step explanation:
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
Air? Unless you mean like a toy boat? IDK, I do know that huge ships like the Titanic are able to float because they have trapped oxygen. Think about if you're swimming; often when you hold your breath you float a bit better than if you were heavily breathing. Sorry i know its not alot to go off of, did i help you a little?
