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.
K so we are solving for y
5x = -y + 6
-6 -6
5x-6=-y
or -5x-6=y
Hope that helped :) if you don't understand something i did, ask and i can try to explain ;)
To find how far the boat is from the bottom of the cliff is you’ll use tan;
Tan18degrees=120/x
x=120/tan18degrees
x=369m
Answer:
z=−1 or z=−3
Step-by-step explanation:
Subtract 3z + 5 from both sides
z2+7z+8−(3z+5)=3z+5−(3z+5)
z2+4z+3=0
Factor left side of equation
(z+1)(z+3)=0
Set factors equal to 0
z+1=0 or z+3=0
z=−1 or z=−3
