Answer: 10x³
<u>Step-by-step explanation:</u>
n=0 1
n=1 1 2 1
n=2 1 3 3 1
n=3 1 4 6 4 1
n=4 1 5 10 10 5 1
The second term of the expansion is: 5(a)³(b)
= 5(x)³(2)
= 10x³
Answer:
Step-by-step explanation:
m∠ JHI + m∠GHJ = 180 { linear pair}
m∠JHI + 90 = 180
m∠JHI = 180 -90 = 90
In ΔGHJ and ΔJHI,
GJ = IJ { given}
JH = JH {common}
m∠ JHI = m∠GHJ { above proved}
ΔGHJ ≅ ΔJHI { Angle Side Side congruence}
Answer:
an hour
Step-by-step explanation:
80 divided by 80... 1.
Answer:
see explanation
Step-by-step explanation:
a and 85 form a straight angle and are supplementary, thus
a + 85 = 180 ( subtract 85 from both sides )
a = 95
b and 85 are vertical angles and are congruent, thus
b = 85
c and 85 are corresponding angles and congruent, thus
c = 85
c and d are vertical angles and congruent, thus
d = 85
In conclusion
a = 95, b = 85, c = 85, d = 85
