Answer:
(x, y, z) = (49, 58, 122)
Step-by-step explanation:
The same-side exterior angles have a sum of 180°.
(x +9) +(3x -25) = 180
4x -16 = 180
x -4 = 45
x = 49
Vertical angles are congruent:
y = 49 +9 = 58
z = 180 -y = 122 = 3(49) -25
The values of x, y, and z are ...
Answer:
12 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = h(a + b)
where h is the height and a, b the parallel bases
here h = 3, a = 3 and b = 5, hence
A = × 3 (3 + 5) = 1.5 × 8 = 12 cm²
C. 8.64m^2 because one face of the cube has a surface area of 1.44m^2 (1.2*1.2) and a cube has 6 sides (6*1.44).
