a) 15.6b) 12c) 36d) 51.6============================================
Explanations:
Part (a)
The area of a triangle formula is A = 0.5*b*h where b and h are the base and height. You could use 1/2 in place of the 0.5
We're focused on the blue shaded triangle, which is the "floor" so to speak of this pyramid. To find the floor area, we will use b = 6 and h = 5.2 and we get
A = 0.5*b*h = 0.5*6*5.2 = 15.6
For this problem, all areas are in square inches as denoted by the [tex]\text{in}^2[/tex]
If you're curious where the b = 6 came from, it's because all sides of the equilateral triangle are the same length.
Note: The base and height of a triangle are always perpendicular.
----------------------
Part (b)
Focus on any single non-shaded triangle. Let's say we focus on the upper triangle. We have b = 6 and h = 4. It then leads to the area A = 12 sq in. This is the area of one lateral face.
------------------------
Part (c)
The instructions state that the lateral faces are congruent triangles, aka they are identical triangles. So that means we have three copies of the same area we found back in part (b), which was 12. Therefore, the lateral surface area is 3*12 = 36 square inches. As your teacher mentions, we do not include the shaded triangle as part of this result (that will happen in part d below).
------------------------
Part (d)
We add the results of parts (a) and (c) together to get the full surface area. This is the total area of the flat net, and it corresponds directly to the full surface area because we fold up the 2D figure to get the 3D one.
The total surface area is 15.6+36 = 51.6 in^2
--------------------------
Side note: Another name for "triangular pyramid" is "tetrahedron". The "tetra" means "four", and "hedron" means "face".

Answer:
D. Subtract the sum of the three test scores from the product of 75 and 5, and divide the result by 2
Step-by-step explanation:
Alright imma try and make this as simple as possible.
My steps:
1) follow the answers steps:
(100 + 85 + 70) - (75 • 5) = -120
-120 divided by 2 = -60
Now, yes the answer is negative but check this out!
3) add 60 twice to 100, 85, and 70: ( 100 + 85 + 70 + 60 + 60) = 375
4) then divide 375 by 5: 375 divided by 5 = 75
Which is our mean! And there you have it! I really hoped this helped and your not confused. Good luck! :)

Step-by-step explanation:
We use Pythagorean Theorem. They have 2 legs that form a right angle. Since the helicopter is cutting short on distance, it will make a diagnal line to reach from one end to the other. To use Pythagorean Theorem, we follow this formula: A squared + B squared = C squared
Our A is 9 and B is 12. We square these by multiplying them by themselves. 9x9=81 and 12x12=144
144+81=225
The next thing we do is find the square root of 225 to find the distance that the helicopter traveled. √ 225 = 15. Thus, the helicopter traveled 15 miles to the other end of the chase.

We're provided : In right angled triangle PQR , The length of of PR & length of PQ are 10 cm & 6 cm respectively & we're asked to find out the length of OR.You need to know : The longest side, which is the opposite side of right angle is the hypotenuse ( h ) . When the reference angle is not given , You can assume the remaining sides either perpendicular ( p ) or base ( b ) .Here , Hypotenuse ( h ) = 10 cm , Base ( b ) = ? & Perpendicular ( P ) = 6 cmBefore solving, You will have to know : The square of the hypotenuse of a right - angled triangle is equal to the sum of square of the remaining two sides.[tex] \large{ \tt{❁ \: LET'S\: START}} : [/tex]
[tex] \boxed {\large{ \bf {\: ♕ \: {h}^{2} = {p}^{2} + {b}^{2} }}}[/tex]
- Plug the known values and then simplify !
[tex] \large{ \tt{ ↦ \: {10}^{2} = {6}^{2} + {b}^{2} }}[/tex]
[tex] \large{ \tt{↦100 = 36 + {b}^{2} }}[/tex]
