<h3>
Answer: (5/9, -7/6)</h3>
=======================================================
Explanation:
Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.
The coordinates of point B are x = 5/3 and y = -7/2
So we have
(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate
and
(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate
The point (5/3, -7/2) moves to (5/9, -7/6)
See the attached figure which represent the rest of the question.
The rest of the question is the attached figure.
==============================================
As shown in the attached figure:
(1) ΔMNL is a right triangle at ∠MNL and ∠NML = 58°
∴ ∠L = 180° - (90°+58°) = 32°
(2) ΔQNL is a right triangle at ∠QNL and ∠QLN = 32°
∴ ∠Q = 180° - (90°+32°) = 58°
So, for both of ΔMNL and ΔQNL
1. ∠NLM = ∠ NLQ = 32°
2. ∠Q = ∠M = 58°
3. side NL = side NL
∴ ΔMNL is congruent to ΔQNL by AAS=======OR=======So, for both of ΔMNL and ΔQNL
1. ∠MNL = ∠QNL = 90°
2. side NL = side NL
3. ∠NLM = ∠ NLQ = 32°
∴ ΔMNL is congruent to ΔQNL by ASA=====================================
So, the correct answer is the first option
Yes, they are congruent by either ASA or AAS
Answer:
-33.6
Step-by-step explanation:
1. Solve inside the brackets = 4.2
2. Multiply that by -8 = -33.6
Well the volume of dirt she needs to remove is equal to length*width*height=6.2*4.9*0.225=6.8355
Now let's find how many bags she needs.
To solve for this, simply divide room in bags from total room.
6.8355/0.87=7.857
Thus Zoe has barely enough, but enough bags.
