Answer:
CD ≅ CD, Reflexive property
Step-by-step explanation:
We want to show the triangles are similar by SAS. We've already proven that one pair of their sides are congruent (AC ≅ BD), and that one pair of their angles are congruent (∠CDE ≅ ∠DCE), so we need to show that the next pair of sides are congruent.
Answer:
<u>Equation of a circle:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center and r- radius
<u>Substitute the given values to get the equation of this circle:</u>
- (x - (-5))² + (y - (-9))² = 7² ⇒
- (x + 5)² + (y + 9)² = 49
Answer:
107.500
Step-by-step explanation:
5.450.000-75.000=5.375.000
5.375.000:12 1/2=5.375.000:25/2=5.375.000*2/25=430.000
430.000:4=107.500
+ and - ,
* and :
are inverse operations
Where it is an operation and the result is a number , we have to do the inverse operation for finding the initial number.
verifying :
107.500*4*12 1/2+75.000=5.450.000
