Answer:
From the given graph, it is clear that at x = 4, the corresponding y-value of the graph is y = 1
Therefore, we conclude that:
Step-by-step explanation:
Given:
A graph is given
To determine:
g(4) = ?
In other words, from the given graph, we need to determine the value of y at x=4
Finding g(4)
From the given graph, it is clear that at x = 4, the corresponding y-value of the graph is y = 1
Therefore, we conclude that:
Answer:
The area of the triangle is 7.5 unit²
Step-by-step explanation:
Here we have the coordinates given as
(-3, 5) (-3, 8) and (2, 5)
Let us call the points A = (-3, 5)
B = (-3, 8) and
C = (2, 5)
Therefore the lengths of the sides of the triangle are
AB = a = 
AC = b = 
BC = c = 
Therefore the Area can be derived from Heron's formula which is
A = 
where s = semi perimeter or (a + b + c)/2
Therefore, plugging the values, we get
s = (3 + 5 + √34)/2 = 6.9155≈6.92
A = 
= 7.499≈7.5.
Answer:1.) m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2.) 24° + x + m∠C = 180°
3.) x = 156° - m∠C
Step-by-step explanation:
1. m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2. 28°+x−4° + ______ = 180°
24° + x + m∠C = 180°
3) x = 180° - 24° - m∠C
x = 156° - m∠C
Hello,
Let 's n the number of sides,
R the radius of the circonscrit circle,
c the side of the polygon (c like côté)
Angle in the center is 360/n and its half is 180/n
(c/2)/R=sin(180/n)
Inside angles are (180-360/n)/2 = 90-180/n (°)
