1) False
Adjacent angles must share a common side/ray.
2) B and D
Adjacent angles are those that are directly next to each other and share a common side.
3) C
Angles 1 and 2 are congruent. Angles 3 and 4 are congruent. Both of these pairs have angles that are opposite each other.
4) B
Angles 1 and 2 add up to 180. Angles 3 and 4 add up to 180. Both of these pairs of angles are supplementary.
5) A
These angles are directly next to each other and share a common side.
Hope this helps!! :)
Answer: B and D
Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080
The surface area is the area of all the surfaces. Let's find the area of the square and the four triangles and add them together:
Square:
Triangles 1, 2, 3, & 4:
Now add them all up:
So the surface area of the square pyramid is 340 square inches.
Answer:
y = -7x + 16 and y = -2x - 9
Step-by-step explanation:
Of the five equations the only ones that exist at the point, (5, -19) are y = - 7x + 16 and y = -2x - 9 (Test them out yourself!).
Hope this helps :)
I think its b but it could be d if i were u i would go w/ answer b hope dis helps
