∠A and ∠B are supplementary so that means they have a sum of 180°.
m ∠A=3(m ∠B) and m ∠B=?
m ∠A + m ∠B=180°
3 (m ∠B) + m ∠B=180°
4 m ∠B=180°
4/4 m ∠B=180°/4
m ∠B=45° and m ∠A=3(m ∠B)=3 (45)=135°
Answer:
a=-5
Step-by-step explanation:
divide both sides by -2: -5=a
a=-5
Answer:
113
Step-by-step explanation:
The supplement of angle 3 is congruent to 67, because they are corresponding angles. After you subtract the supplement from 180, you should get angle 3
180-67=113
The points <span>M(10, 12), N(23, 16), O(12, 17), and P(11, 25) is located in Quadrant I.
The points </span><span>Mꞌ(12, −10), Nꞌ(16, −23), Oꞌ(17, −12), and Pꞌ(25, −11) is located in Quadrant IV
So the degree of rotation is 90 degrees</span>
