Two angles of a quadrilateral measure 130 and 10. The other two angles are in a ratio 2.9. What are the measures of those two a

andrey2020 [161]

Answer:

check: 50+160+130+20 = 360

50:160 = 5 : 16

Step-by-step explanation:et the smaller of the unknown angles be 5x and the larger of the two be 16x

so 130+20+5x+16x = 360

21x = 210

x = 10

so the two missing angles are 50° and 160°

check: 50+160+130+20 = 360

50:160 = 5 : 16

What is - 4i ^ 19, simplify

german

Answer:

$"i"$

Step-by-step explanation:

$i =\sqrt{-1} \\i^{2}= -1\\\\i^{3}= -i\\\\i^{4}= 1\\\\i^{5}= i\\$

the cycle repeats every 4

19/4 = 4.75

16 is divisible by 4 plus three more

thus $i^{19} = -i$ but you problem has a minus in front so "i"

Answer:

<u>Rectangle area:</u>

A = lw

<u>Given:</u>

l = 12 ft, A = 300 ft²

12w = 300
w = 300/12
w = 25 ft

<u>Perimeter is the sum of side lengths:</u>

P = 2 1/4 + 5 2/5 + 5 17/20 =

2 + 5 + 5 + 1/4 + 2/5 + 17/20 =

12 + 5/20 + 8/20 + 17/20 =

12 + 30/20 =

12 + 1.5 =

13.5 ft
