Answer:
Step-by-step explanation:
<em>It is assumed the three angles are interior angles of a triangle.</em>
Given
We know the sum of interior angles of a triangle is 180°.
Use this property to find the missing angle measure:
- m∠1 + 39° + 85° = 180°
- m∠1 + 124° = 180°
- m∠1 = 180° - 124°
- m∠1 = 56°
Answer:
Option D is correct
(1,2,4)
Step-by-step explanation:
Given is a table as
x y
2 1
3 4
4 4
5 2
------------------------
Here we are asked to find the range
Range is the values of y which have preimages as x
Here we find that the items y=1,4,2 have preimages in x
Hence range = (1,4,4,2)
Write in order and write only once the repeated values to get range as
Range = {1,2,4}
Option D is right
Answer:
She got a %40 discount
Step-by-step explanation:
Answer:y=63
Explanation:
1/4(8y—4.8)=2(0.9y+5.4)+3/5
2y-1.2= 1.8y + 10.8 + 3/5 |add 1.2 and minus 1.8y from both sides
2y-1.8y = 10.8 + 3/5 + 1.2
0.2y = 12+3/5
0.2y = 63/5 |divide both sides by 0.2
Y= 63
