Answer:
y = 18
Step-by-step explanation:
Since the triangles are similar, the corresponding sides are in proportion, that is
= 
, substitute values
= 
( cross- multiply )
14y = 252 ( divide both sides by 14 )
y = 18
Next to angle x is 102° and is you add 102 to angle x it has to equal 180 because that’s the value of half the circle so you do 180-102 which will give you 78
Answer:
Step-by-step explanation:
The first is 2, the second is 6 and the third is 14.
Answer:
32 ounces
Step-by-step explanation:
18+14=32
32 is the total
Answer:
(3,8): No, (-1,-11): Yes, (2,7): Yes, (0,-6): No
Step-by-step explanation:
Basically, you just substitute x and y with the numbers given.
18x - 3y = 15
y = 6x - 5
(3,8):
18(3) - 3(8) = 15
54 - 24 = 30 It is not equal to 15, so it does not work.
y = 6x - 5
8 = 6(3) - 5
8 = 13 It is not equal to 8, so it does not work.
Therefore, (3,8) is not a solution.
Try this for every pair and you will find that (-1,-11) and (2,7) are solutions.
I hope this helps!
