Answer:
<h3>
10 and 20</h3>
Step-by-step explanation:
x - the smaller number
x 10 - the larger number
5(x+10) - five times the larger number
6x - 6 times the smaller number
6x+40 - 40 more than 6 times the smaller number
6x + 40 = 5(x + 10)
6x + 40 = 5x + 50
-40 -40
6x = 5x + 10
-5x -5x
x = 10
x+10 = 10 + 10 = 20
Answer:
<BKC
Step-by-step explanation:
m<DKC = 20°
m<BKD = 70°
m<BKC = m<DKC + m<BKD (angle addition postulate)
m<BKC = 20° + 70° (Substitution)
m<BKC = 90°.
Therefore, the angle that equals 90° in the given figure is angle BKC.
