Answer:
A
Step-by-step explanation:
● first one:
The diagonals of a rhombus are perpendicular to each others wich means that they form four right angles.
STP is one of them so this statement is true.
● second one:
If ST and PT were equal this would be a square not a rhombus.
● third one:
If SPQ was a right angle, this woukd be a square.
● fourth one:
Again if the diagonals SQ and PR were equal, this would be a square.
Answer:
i
Step-by-step explanation:
because you can't technically can't find the square root of -1, so it's an imaginary number
Answer:
8 nickels and 9 dimes
Step-by-step explanation:
If all were dimes, the value would be $1.70. It is $0.40 less than that. Changing a dime for a nickel reduces the value by $0.05, so there must have been $0.40/$0.05 = 8 such changes.
There are 8 nickels and 9 dimes.
_____
<em>Check</em>
8 · 0.05 + 9 · 0.10 = 0.40 + 0.90 = 1.30 . . . the answer checks OK

-3t+3=6
-3t=3
t=-1
Answer:
x = 9
Step-by-step explanation:
Since the angle is bisected by rhe segment then the ratio of the sides to the corresponding parts of the base are equal, that is
= 
( cross- multiply )
20x = 180 ( divide both sides by 20 )
x = 9
