Let n = one of the angles
Let 2n -30 = the other
n+ 2n -30 =90⁰ (because they are complementary)
Combine like terms -- 3n -30 = 90
Add 30 to both sides of the equation
3n=120°
Divide both sides by 3 and n=40° 2n -30 = 80 -30 = 50°
So one angle is 40° and the other is 50° and those angles are complementary.
Answer:.
Step-by-step explanation:
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.
Answer:
= 6/5 or 1 1/5 or 1.20
Step-by-step explanation:
= 1/2(12÷3)3/5
= 1/2 (4) 3/5
= 2 x 3/5
= 6/5
