Answer:
14.18 units & 4.88 units
Step-by-step explanation:
The right triangle in this problem is shown in the attached image.
Using trigonometry, the adjacent leg would be 15 Cos 19°
and the opposite leg would be 15 Sin 19°
Thus,
one leg is 15 Cos 19 = 14.18 units, and
another leg is 15 Sin 19 = 4.88 units
Answer:
(0,-3)
Step-by-step explanation:
hi, with this we can just do substitution (substitute x for y+3)
6(y+3)-5y=15
evaluate
6y+18-5y=15
y+18=15
y=-3
then we plug that in
x=-3+3
x=0
Answer:
8 units
Step-by-step explanation:
find the distance of the lines through coordinates given
distance formula: 
i) CD=
CD=
CD=4 units
ii) DE=
DE=
DE=
DE= 2 units
iii) ED=
ED=
ED=
ED= 2 units
perimeter of polygon= 2 units+ 2 units+ 4 units
=8 units
Answer:
x = 20
Step-by-step explanation:
These angles are equal to each other because they are vertical angles.
Hence, we can equal the two measurements together to solve for x:
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
Check your work:
3(20) + 50 = 6(20) - 10
60 + 50 = 120 - 10
110 = 110
Correct
