Line BD is perpendicular to line AC. both angles ADB and CDB are right angles.
4x+10=90
subtract 10 from both sides
4x=80
divide both sides by 4 to isolate x
x=20
plug in 20 for x in the equation (x+11) to find the measure of angle c
20+11=31°
the measure if angle c is 30°
Answer:
5 units^2
Step-by-step explanation:
Area of a triangle =
plugging in:
You can "add" like you say or you could just call it subtracting. If you subtract 5 from 5 you still get zero. Then on the right side, you would do the same. You would subtract 5 from 12 getting x, which is 7.
If you added you would still get the same answers but it is easier to say just subtract. Anything you do to the left, do to the right.
Hope this helps :)
