Answer:
α = 20.5
β = 69.5
c = 90
Step-by-step explanation:
we have to make 2 equations one for the relationship between the angles and another for the sum of all the angles
β and α are the acute angles
β = 3α + 8
α + β + 90 = 180
we replace in the second equation the value of β by (3α + 8)
α + β + 90 = 180
α + (3α + 8) + 90 = 180
a + 3a = 180 - 90 - 8
4a = 82
a = 82/4
a = 20.5
now we replace the value of b in the other equation
β = 3α + 8
β = 3 * 20.5 + 8
β = 69.5
Answer:
31 days
Step-by-step explanation:
125 kg/1 day = 3875 kg/x days
x(125) = 3875
x = 3875/125
x = 31 days
Answer:
true
false; exponent should be -7
false; exponent should be 16
true
Step-by-step explanation:
Area = Length x Width
Given that length = 192cm² and the length = 12 cm, we plug these values into the equation and solve for the width:
192 = 12 x width
192 = 12width
width = 192 ÷ 12
width = 16 cm
Answer: Width = 16 cm
