It could mean something with measurements
Answer:
69.75 square inches
Step-by-step explanation:
Add the top and bottom lengths then divide by 2 before multiplying it with the height
1/2x(3+12.5)=7.75
7.75x9=69.75
Answer:
7
Step-by-step explanation:
3(3-2)+4
3(1)+4
3+4
7
Answer:
He stepped back 59.71 feet.
Step-by-step explanation:
Start by making 2 triangles. One has 68 degrees as the acute angle at the base of the triangle and the other has 41 degrees as the acute angle at the base of the triangle. The side opposite of said angle on both triangles will be 80, the height of the tree. You're solving for the bottom (horizontal) side for both triangles.
For the triangle with an acute base angle of 68, the formula to solve for the horizontal side is tan(68) = 80/x.
Get x by itself to get 80/tan(68) = x
x = 32.32.
For the next triangle, the equation is the same but the angle is changed to 41.
tan(41) = 80/x
80/tan(41) = x
x = 92.03
Finally, subtract the smaller distance from the larger:
92.03 - 32.32 = 59.71 steps.
Answer:
80
Step-by-step explanation:
Triangles angles measure 180 degrees when added.
You have 2 at 50 which makes 100 degrees.
180 - 100 = 80 degrees
