The sum of angles in triangle is equal to 180 degrees, so
<R =180-56-30
<R=94
Step-by-step explanation:
-2j < -14
Divide both sides by -2:
j > 7. (D)
Answer:
The area of a rhombus is
square units.
Step-by-step explanation:
Side length of rhombus = 6 units.
Interior angle of rhombus = 120°
another Interior angle of rhombus = 180°-120° = 60°.
Draw an altitude.
In a right angled triangle



Multiply both sides by 6.

The height of the rhombus is
.
Area of a rhombus is



Therefore, the area of a rhombus is
square units.
Answer:
2 feet
Step-by-step explanation:
Let
x ----> the uniform amount added to each side
we know that
The algebraic expression that represent this situation is

solve for x
Apply distributive property

solve the quadratic c equation
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The solution is x=2 ft
