Answer:
3³ = 27
Step-by-step explanation:
The applicable rules of exponents are ...
a^b = 1/a^-b
(a^b)(a^c) = a^(b+c)

look at the row and times it by 6x5= 30
Answer:
360cm²
Step-by-step explanation:
area of the parallelogram = base x height
base = 40 -10= 30cm
height = height of the triangle
A = 30*12= 360
Answer:
67.5°, 107.5°
Step-by-step explanation:
For supplementary angles, their sum equals 180°.
Let x be the first angle and y be the second angle, then
x + y = 180°.
It is given that x = y + 45°.
So x + y = 180°
substituting x into the equation, we have
y + 45° + y = 180°
simplifying, we have
2y + 45° = 180°
collecting like terms, we have
2y = 180° - 45°
2y = 135°
dividing through by 2, we have
y = 135°/2
y = 67.5°
Since y = 67.5°
then x = y + 45°
x = 67.5° + 45°
x = 107.5°
