Answer:
90°
Step-by-step explanation:
since PQ is the diameter of the circle, m <em>L</em><em> </em>PRQ = ½ × 180° = 90°.
so, as a supplementary to <em>L</em><em> </em>PRQ, the value of angle QRS = 180 - m <em>L</em><em> </em>PRQ = 180-90 =90°
Answer:
x = 20
Step-by-step explanation:
→ Remember how many degrees are on a straight line
180°
→ Set up an equation
2x + 70 + 3x + 10 = 180
→ Simplify
5x + 80 = 180
→ Minus 80 from both sides
5x = 100
→ Divide both sides by 5
x = 20
47, 57, 67, 77 are the numbers.
