Zak wants to work out the area of this triangle. 14 cm
8 cm
- 12 cm
Here is his working.
12 x 8 = 96 cm
What is wrong with his method?

What is the relationship between all triangles that can be drawn given the same three angles

Abag contains 4 red, 7 blue and 5 yellow marbles. event a is defined as drawing a yellow marble on the first draw and event b is defined as drawing a blue marble on the second draw. if two marbles are drawn from the bag, one after the other and not replaced, what is p(b|a) expressed in simplest form? a. 7/16 b. 7/15 c. 14/16 d. 14/15

I’m still confused on how to work the percentages
