Question

Pls help a sista again..

Answer 1

38 degrees

Explanation:

DTU added to STD will make STU so we can make an equation for this

(4x+10)+(102)=19x+7

4x+112=19x+7

-4x. -4x

112=15x+7

-7. -7

105=15x

/15. /15

7=x

now to find DTU we fill in x

4(7)+10

28+10

38 degrees

hopes this helps
