Answer:

(a)

x = 18.5

y = 22.5

(b)

x = 10

Step-by-step explanation:

Solving (a):

7x - 19 and 3x + 14 are interior angles.

So:

7x - 19 + 3x +14 = 180

Collect like terms

7x + 3x = 180 - 14 + 19

10x = 185

x = 18.5

7x - 19 and 5y - 2 are equal angles --- corresponding angles

So:

5y - 2 = 7x - 19

Make 5y the subject

5y  = 7x - 19+2

5y  = 7x -17

Make y the subject

y = \frac{1}{5} (7x - 17)

Substitute x = 18.5

y = \frac{1}{5} (7*18.5 - 17)

y = \frac{1}{5} (112.5)

y = 22.5

Solving (b):

The triangle is right-angled.

So:

5x + 3 + 2x + 17 + 90 = 180

Collect Like Terms

5x + 2x = 180 - 90 - 17-3

7x = 70

x = 10

P and a are both prime numbers. Find the values of p and q so that 6*54*p/q is a perfect cube.
daser333 [38]

6x54= 324

6x50=300

6x4=24

300+24=324

The previous nearest cube root is 216 and the next cube root would be 343.

p/q could be any prime number which there are a lot of.

im going to say p is 1 and q is 3

next you would divide 1 by 3

1/3=0.666666667

324x0.666666667=216 exact
