Given: ∠ DEF
To construct: ∠TSZ ≅ ∠DEF
Construction: Consider the attachment
Step-01: Draw a line XY and choose a point S on it as a vertex of the required angle. Further marks point T such that DE = ST
Step-02: Take an arc AB from point E in ∠DEF of any length and draw at point S which cuts at point P on XY line.
Step-03: Take another arc of length AB from point B in ∠DEF and draw from point P which cuts to the previous arc at Q.
Step-04: Now, join the point SQ and extend up to Z such that EF = SZ
Hence, ∠ TSZ will be the required congruent constructed angle to∠DEF
Answer:
The cost of one bear is <u>$47,000</u>.
Step-by-step explanation:
The question is incomplete and the data is missing so the complete question with data is below with attached files:
To celebrate there 125 anniversary, a company in Germany produced 125 very expensive teddy bears. The bears,known as the "125 karat teddy bears", are made mohair,silk and gold thread and have diamond and sapphire eyes.
The chart shows the approximate cost of " 125 teddy bears". Based on the pattern, how much does one bear cost?
Now, to get the cost of one bear.
So, we solve it by using unitary method:
If 4 bears cost = $188,000.
Then 1 bear cost =
Thus, cost of one bear is $47,000.
Now, we check it by using another pattern of the data:
If 7 bears cost = $329,000.
Then 1 bear cost =
Hence, the cost of one bear is $47,000.
Therefore, the cost of one bear is $47,000.
