PLEASE HELP!GIVEN: angleSRT is equivalent to angleSTR, m angleSRT = 20, m angleSTU = 4xH
Accepted Solution
A:
x = 40
This is because STR and STU make up a straight line (180 degrees). Because STR is congruent to SRT, then we know it is 20 degrees, leaving the other 160 degrees for STU. When we divide away the 4, it gives us x = 40.
