The congruent complement theorem states that angles AGI and BGH are congruent. This is because there is a pair of vertical angles next to angles AGI and BGH, and we also know that AGI and its adjacent angle add up to 90, and the same goes for BGH and its adjacent angle.
Hope this helps! :)
2x² +8y = 121.5
<span>8y = 121.5 - 2x</span>²
and,
<span>x</span>²<span>-8y = 121.5 </span>
<span>-8y = 121.5 -x</span>²
<span>8y = x</span>²<span>-121.5 </span>
<span>Now, equate the two 8y's </span>
<span>121.5-2x</span>²<span> = x</span>²<span> -121.5 </span>
<span>-3x</span>²<span> = -121.5-121.5 </span>
<span>-3x</span>²<span> = -243 </span>
<span>3x</span>²<span> = 243 </span>
<span>x</span>²<span> = 81 </span>
<span>x = ±9</span>

Answer:
571,725 J
Step-by-step explanation:
KE = 1/2mv²
KE = 1/2(1050 kg)(33 m/s)² = 571,725 J
Answer:
12
Step-by-step explanation:
You need the GCF of 48 and 60
48 = 2 x 2 x 2 x 2 x 3
60 = 2 x 2 x 3 x 5
Both have 2 x 2 x 3, so the answer is 12
Answer:
A 31/45
Step-by-step explanation:
A 31/45=0.6888 (this is the awnser as the line on top means repeating)
B 682/999=0.682 (0.68 rounded)
C 62/99=0.62626 (repeating)
D 2/3=0.66666 (Or 0.67 rounded)
