Answer:
(-2, 4)
Step by step explanation:
-2 is the x coordinate and 4 is the y coordinate
(x, y) = (-2, 4)
There is your answer
If it is 1. right angled triangle sum of three angles is 180° given is 70° other is 90° remaining is 180°-(70°+90°)= 20°
The value of three angles are 70°, 90°,20°

I tweaked with #6 because the hypotenuse is usually the biggest number.
Answer: 3^4 · 3^-9 = 3^4 · 1/3^9
Step-by-step explanation:
Answer:
34º
Step-by-step explanation: so basically you know a complementary angle is 2 angles that make a straight line and a vertical angle crosses which means 2 angles are congruent to each other so I drew a line that bisected the angle by drawing a line that cut through the right angle and i extended a line down from the right angle so now I have a vertical angle and a complementary so from here I labeled each angle <1 <2 <3 If I know angle 3 is 56º then I know 56 plus __ equals 90º I then subtracted 56 from 90 and I got 34 and since I am trying to figure out what angle 1 is I know that angle 1 and 2 are vertical angles therefore I know they are congruent to each other so <1 = 34º
