Step-by-step explanation:
if a rhombus has 4 right angles it wpuld be a square
Answer:
2.
Step-by-step explanation:
Rotating a figure about the midpoint of its diagonal, the figure will coincide with its pre-image two times: at 180° and at 360°.
This is different than rotating about the origin; for a rotation about the origin, a 180° rotation does not always coincide with the pre-image.
hope that answers ur question :))))
Answer:
$13.75 should be your answer
Step-by-step explanation:
Note that 45 nickles = 45 x 5 = 225 cents
Note that 10 quarters = 10 x 25 = 250 cents
Note that 18 half-dollars = 18 x 50 = 900 cents.
225 cents = $2.25
250 cents = $2.50
900 cents = $9
Add
2.25 + 2.50 + 9 = 13.75

Answer:
x=25, 120
Step-by-step explanation:
The two angles form a straight line so they add to 180
60 + 4x +20 =180
Combine like terms
4x+80 = 180
Subtract 80 from each side
4x+80-80 =180-80
4x= 100
Divide by 4
4x/4 =100/4
x= 25
The exterior angle is
4x+20 = 4*25+20 =100+20 =120
