Remember that the angles in a triangle add to 180 degrees. So, to solve, you add the two angles you have and subtract that difference from 180.
Answer:
I think the option B suits the most
Step-by-step explanation:
-40 4 10 20 I think this is the answer I’m not sure
The inside of a trapizoid is always 360 degrees. SO 110+ 130 + x + x-3 = 360
240 + 2x - 3 = 360 236 + 2x = 360 2x = 124 x = 62. I'll leave what the other angle is to you but that is the answer. Hope that helps. if you don't get the steps i took just ask!
You would use TOA from trig so your equation would be
Opposite = tan(angle) X adjacent
X = tan(15) X 400
It should equal 6000 but check that using the equation on a calculator :)
