Step-by-step explanation:
first of all, as the sum of all angles in a triangle is always 180°, the missing angle B is
B = 180 - 89 - 30 = 61°
the law of sine is
a/sin(A) = b/sin(B) = c/sin(C)
where the sides are always opposite of the associated angles.
14/sin(61) = AB/sin(30) = BC/sin(89)
BC = 14×sin(89)/sin(61) = 16.00451901...
so, 16 is the correct answer.
Answer:
Area = 8 square units
Step-by-step explanation:
use the formula, A=(a+b)
/2*h
A=area
a=base (5)
b=base (3)
h=height (2)
A=(5+3)/2*2
A=8/2*2
A=4*2
A=8
3/10 or 0.3 because when you solve it step by dividing radical of 9 from 100 and then simplifying it you end up with this answer.
Given:
A line AB joins the points A (3,4) and B (5,8).
To find:
The midpoint of the line AB.
Solution:
Midpoint formula:
A line AB joins the points A (3,4) and B (5,8). So, the midpoint of line AB is
Therefore, the midpoint of the line AB is (4,6).
