Answer:
18, 7.4 (if its 12.6) and 52, 92 (if its 12x6)
Step-by-step explanation:
Answer: 95°
Step-by-step explanation: We are given information for Angles 1 and 4, which happen to be vertical angles, meaning they are congruent. Because of this, we can say 3x+10=4x-15, therefore x=25. Angles 1,2,3 and 4 must add up to 360°, and since we know angles 1 and 4 are 85° (3*25 + 10 = 85), we can find angles 2 and 3. 360° - 85° - 85° = Angle 2 + Angle 3. Angle 2 + Angle 3 = 190, and because Angles 2 and 3 are vertical angles and therefore congruent, we can divide 190 by 2 and get that Angles 2 and 3 equal 95°. Because lines b and c are parallel, any corresponding angles created by a transversal are congruent. This basically means Angles 3 and 7 must be congruent, therefore Angle 7 = 95°
Congruent - same meaning as equal
Vertical Angles - each of the pairs of opposite angles made by two intersecting lines.
Answer:
Number 45 increased by 10% (10 percent) of its value (percentage increase) and calculated absolute change (actual difference). Answer: number percentage increased = 49.5, absolute change (actual difference) = 4.5 Introduction. Percent, p% p% = p / 100 = p ÷ 100.
