Answer:
B) supplementary angles
C) straight angle
Step-by-step explanation:
There is a straight line, and when an angle is a straight it means its 180 degrees which makes it a supplementary angle and a straight angle.
There are no angles that are 90 degrees so its not complementary or a right angle.
Answer:
62.4 square centimeters
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The surface area of the triangular pyramid is equal to the area of the triangular base plus the area of its three lateral triangular faces
In this problem the triangles are equilateral, that means, the
surface area is equal to the area of four congruent equilateral triangles
so
![A=4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=A%3D4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have

substitute
![A=4[\frac{1}{2}(6)(5.2)]=62.4\ cm^2](https://tex.z-dn.net/?f=A%3D4%5B%5Cfrac%7B1%7D%7B2%7D%286%29%285.2%29%5D%3D62.4%5C%20cm%5E2)
Answer:
It's f(x)=10x+8
Step-by-step explanation:
Because it says every hour not every half hour and the graph changes by 0.5 instead of 1 so m would equal 10

the product will increase by 2n
Answer:
answer down below.
