Answer:
72°
Step-by-step explanation:
So the three angles of a triangle always add up to 180°. This means that
This becomes:
And solves as:
The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.
The measure of the largest angle in the triangle is 72°.
Answer:
x = 23
Step-by-step explanation:
5x - 9 and 2x + 60 are corresponding angles and are congruent , so
5x - 9 = 2x + 60 ( subtract 2x from both sides )
3x - 9 = 60 ( add 9 to both sides )
3x = 69 ( divide both sides by 3 )
x = 23
Use the slope formula.
Subtract the y-coordinates.
Subtract the x-coordinates in the same order.
Divide the difference in y by the difference in x.
slope = m = (y2 - y1)/(x2 - x1)
slope = (5 - 7)/(-2 - (-1)) = -2/(-1) = 2
slope = 2
Answer:
24
Step-by-step explanation:
The equation for the area of a triangle is 1/2 base times height.
Base = 12
Height = 9
Plug that in.
1/2 (12x9)
To get 24.
