When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent
When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)
0.000000109 in scientific notation will look as it follows:
1.09 * 10^-7
or
<span>
1.09 E-7
It's the same as 1.09 * (-10000000)
I hope it'll give you some clue of scientific notation with decimals.</span>

1/cos * cos/sin =cscx
cos/sincos=csc
1/sin=csc
Answer:
x=55
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees
<A + < B + <C = 180
x + 75+ 50 = 180
x + 125 = 180
subtract 125 from each side
x = 180-125
x = 55
Answer: C
<u>Step-by-step explanation:</u>
1. DOF and GOH are vertical angles 1. Given
2. m∠DOF = m∠GOH 2. Vertical Angles Theorem
3. ∠DOF = 58° 3. Given
4. 58° = m∠GOH 4. Substitution
