Answer:
vertical angles
∠1 and ∠3 are vertical angles. Their measures are equal, so m∠3 = 90 . ∠1 and ∠2 are supplementary.
Step-by-step explanation:
Remember in every triangle, the sum of the angles adds to 180 degrees. So let us call the smallest angle's measure "A". The largest angle is 3A and the third angle is A+10. So A + 3A + (A + 10) = 180.
Since its every two days the equation would be
3(1.25+3.5)= how many hours the scientist will spend observing the dolphins and sea lions
that equals 14.25 so thats your answer
The answer is 33. Remember all complimentary angles equal 90 degrees so subtract 90 from 57 and the other angle is 33
-3x-3 = 4x-3
-3 = 7x-3
0 = 7x
x = 0
