Answer:
x = 22
y = 35
Step-by-step explanation:
Because its an isosceles triangle, you know the base angles are equal so:
Solving:
subtract 2x from both sides
add 11 to both sides
Next, find the angle measures of the two base angles:
To find y, you know that the interior angles of the whole triangle add up to 180, so you have
solving,
subtract 110 from both sides
divide both sides by 2
#1 There is no area of a cube. There is only a volume.
#2 The formula is
where s is the side.
Substitute 729 in V since that is the volume.
Take the cube root and you will get 9.
So the formula is and the side is 9.
#2 The formula is
Substitute 729 in V since that is the volume.
Take the cube root and you will get 9.
So the formula is
