Answer:
Step-by-step explanation:
5y + 6y + 7y = 18y......any numbers that add(or subtract) to equal 18, stick them before the y....
or it could be : 10y + 10y - 2y = 18y or 5y + 10y + 3y or 30y - 20y + 8y....I could go on forever...lol

Answer:
m arc PQ=66°
Step-by-step explanation:
we know that
m arc PQ=m∠PTQ -----> by central angle (because T is the center of the circle)
m∠RTS=m arc SR ----> by central angle (because T is the center of the circle)
m arc SR=66°
so
m∠RTS=66°
Remember that
m∠PTQ ≅ m∠RTS
so
m∠PTQ=66°
therefore
m arc PQ=66°
Answer:
The answer is A (97.5)
Step-by-step explanation:
Formula Using the Diagonals
That means the two diagonals form two sides of a square that is twice the size of the rhombus. You can find the area in square units of the rhombus by multiplying the lengths of the two diagonals (d1 and d2 ) and dividing by two.
