Answer:
Opposite interior angles of a rhombus are congruent (the same). All 4 of them equal up to 360
Now that the decimal has been removed two places you can divide as if it was a regular division problem.
The appropriate expression is x'y'z, where the apostrophe indicates the complement of the variable.
Answer:
x = 5
Step-by-step explanation:
We have: The sum of the measures of angle M and angle R is 90°
M + R = 90°
M = (5x + 10)°
Plug M into (1)
the equation: (5x + 10)° + R = 90° (2)
R=55° into (2)
(5x + 10)° + 55° = 90°
5x + 10 + 55 = 90
5x + 65 = 90
5x = 25
x = 5
Answer:
initial hieght = 72.4 cm
final hieght = 86.2 cm
change in hieght = 9.8 cm
percentage increase = (9.8 ÷ 72.4 ) * 100 = 13.59 %
