Mathematics
1 answer:
stepladder [879]3 years ago
6 0

Answer:

a = 7.4

b = 9.6

Step-by-step explanation:

set up a proportion to find 'b':

XN / NY = MN / NO

8/b = 13/(b+6)

cross-multiply:

13b = 8(b+6)

13b = 8b + 48

5b = 48

b = 9.6

set up a proportion to find 'a':

XN / XY = MN / MO

8/a = 13/12

cross-multiply:

13a = 96

a ≈ 7.4

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

kobusy [5.1K]
<span>The quotient of two numbers is negative. It must be true that B. one of the numbers is negative.
If neither number is negative, then their quotient will be positive, because both numbers are positive. If both numbers are negative, then their quotient will also be positive.
But since B is correct, their quotient will be negative.
For example: -9/3 = -3</span>
