Step-by-step explanation:

exponent means to multiply the number which has the exponent on it to itself like if 2 has the exponent 3 then that means 2 x 2 x 2

please make me the brainliest!

Elena is correct. Because the number 28 is smaller and above the number two, that means it is the exponent. The exponent, or the power, tells you how many times you multiply the number by itself. For example 2 to the 3rd power or 2 with a small 3 above it would be 2 x 2 x 2 which is 8 instead of 2 x 3 which is 6. I hope this helped you and good luck!

two angles of a triangle measure 45 degrees and 90 degrees what is the third angle measure

Answers

45 degrees. That is a right triangle (90 degrees, 45 degrees and 45 degrees).

45 degrees because a triangle is 180 degrees all around, and if u have a 90 degree angle and 45 degree angle you would add the two angles given then subtract from 180 degrees.
