Answer:
340.63
Step-by-step explanation:
To find the area we need to calculate the height of the triangle and one of its sides. the bisector cuts the 60° angle in two of 30°. In the picture I drew the triangle and the sides we need to calculate are y and h.
We are going to calculate x, y and h with sin law:
Then, the area of the triangle is
A =
Answer:
m>11
Step-by-step explanation:
2(m+3)<-5+3m
2(m+3)>3m-5
2m+6>3m-5
6<3m-5-2m
6<m-5
6+5<m
11<m
m>11
The answer would be 50 if you're doing any form of division on it
Answer:
The axis of symmetry is x = -2 and the vertex is (-2, 9)
Step-by-step explanation:
To find the vertex of the standard form equation, use the formula x = -b/2a. Then substitute -b/2a into the equation and solve for y.
Here a = -1, b = -4 and c = 5.
Substitute the values and solve.
x = -(-4)/2(-1)
x = 4/-2
x = -2
Substitute x = -2.
y = -(-2)^2 -4(-2) + 5
y = -4 + 8 + 5
y = 9
So the axis of symmetry is x = -2 and the vertex is (-2, 9).
2g+10
twice the height is 2g, then add 10
