Hello there, and thank you for posting your question here on brainly.
<em>Short answer: 25.48 x 10^4
</em>
Why?
This equation has a few steps. Simplify the brackets. (2.8 x 10^-2)*(9.1 x 10^6) --> 2.8 x 10^-2 * 9.1 x 10^6 Simplify. (or multiply the two decimals) 2.8 x 10^-2 * 9.1 x 10^6 --> 25.48 x 10^-2 x 10^6 Use the <em>product rule. </em>(the formula is x^y x^z = x^ y+z) 25.48 x 10^-2 x 10^6 --> 25.48 x 10^4

Answer:
The other angle is 58 degrees
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let the other angle be x
x+122 = 180
Subtract 122 from each side
x+122-122= 180-122
x = 58
The other angle is 58 degrees
