hi,
first let's count the marbles : 1+3+2 = 6
so picking a red is 1/6
a green is : 3/6
a bleu is : 2/6
Answer:
x is tangent of 39 = x/ 19, tangent of 39 is 3. 615...... then 19 multiply by 3.615....., x would get 68. 68
Step-by-step explanation:
tangent is opposite over adjacent then put all your numbers in to the formula.
Answer:
15 units²
Step-by-step explanation:
Hi there!
where <em>b</em> is the base and <em>h</em> is the height
Plug in the base (7.5) and height (4):
Therefore, the area of the triangle is 15 units².
I hope this helps!
<2 = 38
An iscolese triangle adds to 180 degrees. Thus, the two base angles, which is <2 & <3 should be half of the result from 180 - 104.
180 - 104 (angles in a triangle add to 180 degrees)
= 76
76 / 2 (iscolese triangle. base angles are equal)
therefore, 38
5*4 equals 20 so her wall is 20 square meters
Given that one litre can cover 10 square meters, she needs 2 litres of paint to cover the wall
