Using the Pythagorean theorem:
AC = √(13^2 - 12^2)
AC = √(169 -144)
AC = √25
AC = 5 cm
Answer:
69
Step-by-step explanation:
Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
Answer:
1/4
2^6 * 2^-8
(the first two)
Step-by-step explanation:
(^-3 * 2^4)^-2 = 1/4
=(1/8(24))^−2
=(1/8(16))^−2
=2^−2
=1/4
2^6 * 2^-8 = 1/4
=64(2−8)
=64(1/256)
=1/4
