Hi I need help with this

Answers

Answer:

55

Step-by-step explanation:

90+35=125. 180-125=55. Answer: 55 degrees.

Answer:

Angle E = B. 55 degrees

Step-by-step explanation:

Every triangle's angles always add up to 180 degrees.

Angle F is marked as a 90 degrees angle, so we can then add 35 and 90 together to get 125.

Then, subtract 125 from 180 to get the measure of Angle E.

180 - 125 = 55

Angle E is measured at: B. 55 degrees.
