Answer:
x = 8
Step-by-step explanation:
Chords AB and BD form an inscribed angle so <ABD = 5x
also given mAD = 80
Since inscribed angles are half the measure of their intercepted arc, angle <ABD is equal to 1/2(80 degrees), which is 40 degrees.
Now you have:
<ABD = 40
5x = 40
x = 8
Answer
x = 8

<h2>
The required "option D) 54 + 42 = 6(9 + 7)" is correct.</h2>
Step-by-step explanation:
We have,
The sum of 42 and 54
= 42 + 54
∴ 42 and 54
42 = 2 × 3 × 7 and
54 = 2 × 3 × 3 × 3
The greatest common factor of 42 and 54
= 2 × 3
= 6
∴ 42 + 54
= 6(7 + 9)
= 6(9 + 7)
Thus, the required "option D) 54 + 42 = 6(9 + 7)" is correct.
Answer:
s=650
Step-by-step explanation:
s=n/2(2a+(n-1)d)
s=20/2[2x4+(20-1)3]
s=20/2(2x4+19x3)
s=20/2(8+57)
s=20/2x65
s=10x65
s=650
33.44 will be the answer rounded to the nearest hundredth.
