Answer:
y = 105°
Step-by-step explanation:
In an isosceles trapezoid
• Any lower base angle is supplementary to any upper base angle
• The lower base angles are congruent
75 and x are supplementary, thus
x = 180° - 75° = 105°
x and y are lower base angles and congruent, so
y = x = 105°
Slope- Intercept Form: y= -4/5x -8
Y Intercept: -8
X Intercept: -10
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b
Then as we know it passes the y axis at (0,-3) so b= -3
So we have y=5x-3
First, determine the distances from the towns.
Town A to Town B: Opposite angle C
d = sqrt ((12 - 7)^2 + (9 - 9)^2)
d = 5
Town B to Town C: Opposite Angle A
d = sqrt ((7 - 1)^2 + (9 - 1)^2)
d = 10
Town A to Town C: Opposite Angle B
d = sqrt (12 - 1)^2 + (9 - 1)^2)
d = 13.6
The angle with largest measure is the one opposite the greatest distance. Thus, the arrangement would be: C, A, B.
Answer:
El volumen es la cantidad de espacio tridimensional que ocupa un objeto. El volumen se mide en unidades cúbicas.
Por ejemplo, el siguiente prisma rectangular tiene un volumen de 181818 unidades cúbicas porque está hecho de 181818 cubos unitarios.
