Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.
The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).
Answer:
2847.5
Step-by-step explanation:
670/4 = 167.5
17 x 167.5 = 2847.5
Answer:
0.30715935334
Step-by-step explanation:
8/6 ÷ 13/3
1.33÷ 4.33
0.30715935334
me need slope and y intercept to get it in y=mx+b form (slope intercept)
Slope is the
difference in y / differences in x
differences in y = 6.5 -3 = 3.5
difference in x = 2 - 1 = 1
so slope is 3.5/1 or just 3.5
(now you can see the answer is c but lets check it by getting the y intercept too)
y intercept
this is when x is 0
the lowest x we see is 1 so if I go bacl to 0 in x the y must for back 3.5
3-3.5 is -0.5
so equation is y=3.5x -0.5 so the closest is c
