Question

A skateboard ramp has a 158° entry angle. Find the measure of ∠1.
-->22°
68°
78°
58°

Answer 1

You know that the angle of a flat line is 180 deg. Looking at the picture 158 + x = 180.
Which makes x = 22 deg.

Answer 2

The sum of all angles in triangle must be 180 also.

90+22 + <1 = 180

<1 = 68 deg

Answer 3

So the answer is 68? or is it 22? It always confuses me at the end

Answer 4

your looking for <1 which is 68 deg

Answer 5

Oh right thanks bunches :)

Answer 6

No problem =D
