Answer:
OK so a triangle has 3 sides and the perimeter around it is 20.6 cm to find the unknown for the length of a side it would be 20.6 ÷3 which is = to 6.86 to 2 decimal places
Step-by-step explanation:
20.6÷3
= 6.86 cm to 2 dp
Answer:
<h2>SU = 3.5</h2>
Step-by-step explanation:
We have the triangle 30° - 60° - 90°.
Right triangles with 30-60-90 angles will have their ratio of the sides as
1 : √3 : 2 (look at the picture).
We have:
SR : SU : RU = 1 : √3 : 2
Therefore RU = 2SR and SU = SR√3.
We have RU = 4. Substitute:
2SR = 4 <em>divide both sides by 2</em>
SR = 2
SU = 2√3 ≈ 2(1.73) = 3.5
Answer:
No
Step-by-step explanation:
A tangent line is a line entirely exterior to the circle except for the one point of intersection that lies on the circle. It does not (and cannot) go through any points inside the circle.
