Answer:
A) Tan 60° = 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4 unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ =
So, Tan 60° =
=
∴() × ( = h
∴ h = 12 unit
C) Area of this triangle = × Perpendicular × Base
= × h ×
∵ Perpendicular h = 12 unit
So, Area = × 12 ×
Hence Area of triangle = 41.569 unit²
ANSWER
Answer:
tanC = 5/12
Step-by-step explanation:
tanC = opp/adj = 5/12
Answer:
7/4 OR 1 3/4
Step-by-step explanation:
49/10 divided by 14/5
49/10 multiplied by 5/14
49x5 / 10x14
245/140
simplified or cancelled out to
7/4 OR 1 3/4
It is a parallelogram, so opposite angles are congruent.
4x = 100°
x = 25°
Sum of angles in a parallelogram is 360°.
360°-100°-100° = 160°
y = 160°/2 = 80°
