If Marcus drew a rectangle with different lengths and widths, then drawing a diagonal will create 2 congruent triangles that are scalene (all 3 side lengths are different) and right (one right angle).
Answer:
30 of 2 points= 60 points
10 of 4 points = 40points so its 30 of 2 points and 10 of 4
Step-by-step explanation:
1 and 2 are right because one has adjacent. 2 vertical angles. Vertical angles mean the same plane and adjacent means two sides of an X.
And or both means we multiply the given probability situations that are mutually exclusive and exhaustive - they cannot occur at the same time.
let P(a)=x
then: P(b) * P(a) =3/4
15/16 * x = 3/4
15x/16 = 3/4
therefore x= 3/4 *16/15
x = 4/5
P(a) = 4/5
hope it's clear
