Step 3: The measure of angle DAB is 60°. Reason: Since DAE is a right angle, and EAB is 30 degrees, 90 - 30 is 60. (Just find the reason that is related to this statement).
Step 4: The measure of angle ABC is 130°. Reason: Same-side Interior Angles Theorem
Step-by-step explanation:
The area of a triangle is always:
A=bh/2 (base times the height divided by 2)
A=3x(2x)/2
A=6x^2/2
A=3x^2
...
40 wpm. Because 160/4=40.
I hope that helped!
