Martha drew the following shape on her
zalisa [80]

Answer:

  right angles and obtuse angles

Step-by-step explanation:

We assume that anything that <em>looks like</em> a right angle <em>is</em> a right angle.

The angles at the left end of each horizontal line are right angles.

The angles at the right end of each horizontal line are obtuse angles.

How do you find the area of a triangle
Anna007 [38]
Salutations!

How do you find the area of a triangle

To find the area of a triangle, you need to know the formula of the triangle to work it out. The following is the formula of the triangle:

hb/2 

H - height

B- Base

You need to multiply the base and height and divide it by 2.

Lets solve a question!

Find the area of a triangle with a base of 32mm and a height32 * 35 of 35mm

Area = hb/2

         = 32* 35

          = 1120

          = 1120/2

           = 56cm^2

Hope I helped (:

Have a great day!
