Right triangle with a length of 10 and 12 feet what is the area

I think it has to include the base and the height but I can tell you the steps on how to do it (To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.)

Step-by-step explanation:

you would use the formula of a triangle witch is 1/2bh and you would get 60

x=60

Step-by-step explanation:

So basically the sum of interior angle of a triangle is 180.

Add all the values and make it equal to 180.

x+3/2x+1/2x=180

Then find x

3x=180

x=180/3

x=60 degrees
