The equation to find the area of a triangle is 1/2bh or 1/2 base*height.
Let’s just insert the known values.
The triangle has a base of 14 and a height of 8.2, so our equation would look like:
1/2(14)(8.2)
Now solve.
7*8.2
57.4
The triangle has an area of 57.4 mm.
Hope this helps!

Well first of you need to know that on a straight line there should be 180 degrees. Also a triangle has 180 degrees in total. Now if this is to scale then you can always measure the angle BCA and explain how you took that away from 180 to get whatever. Assuming otherwise i don't know how one can actually complete this question without any measurements, at least one and it would be something anyone can complete. Even if you didn't have anything it should be a equilateral triangle or isosceles. That way you can work out the inside sides than the exterior. But since it's not, I'm not to sure.

Can an object be in pure translation as well as in pure rotation simultaneously?
Inessa [10]
  <span>"Pure translational" motion means the object is moving from place to place but isn't rotating at all. Mathematically, that means every point on the object has the same velocity vector as every other point on the object. For example, say you have a box that's sliding along the ground, and say each corner on the box is moving at 15 feet per second at an angle of 26 degrees west of north. Since every point on the box has the same velocity vector, the motion is "pure translational." 

"Pure rotational" motion means the object is rotating, but its position in space isn't changing. Mathematically, that means that every point on the object moves in a circle around some axis (usually through the object's center of mass).

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

77 pictures

Step-by-step explanation:

You are trying to find 18% of 430.

18/100 = 9/50 * 430

756/10 = 75.6

77 is the closest choice out of all the other choices.
