Step-by-step explanation:
when B is a subset of C, it means that everything in B is also contained in C. C just contains more than that.
when A is a subset of B, it means in the same way that everything in A is also contained in B. since it is contained in B, it is also contained in C.
so, A is therefore also a subset of C.
Answer:
I'm guessing that makes obtuse triangle
why don't you try draw the triangle
Acute triangle : 0<x<90 degrees
right triangle : x=90 degrees
obtuse triangle :triangles that angles are bigger than 90 but smaller than 180 degrees
reflex angle:bigger than 180 but smaller than 360 degrees
Answer:
1 is 0.6 and 2 is 612 3 is 39.2 and 4 is -3 and 5 is 9/4 or (2 1/4)

Answer:
The measure of
.
Step-by-step explanation:
Given,
AB║CD and
m∠2 = 60°
Solution,
Since, in the figure given in attachment line segment AB is parallel to line segment CD. And t is the transversal line.
The theorem of parallel lines states that,
"If two lines are parallel and cut by a transversal line then the pair of corresponding angles are congruent."
So according to the theorem of parallel lines,∠2 and ∠6 makes a pair of corresponding angle.
And the measure of corresponding angle is equal.
So, m∠2 = m∠6

Thus the measure of
.
