Find the opposite of adding 15. So it would be subtracting 15. So subtract 15 on both sides. So it would have 2/3x on the left and then 2 on the other side. (2/3x=2) Now find the opposite of multiplying 2/3. It is dividing 23/3. So divide 23/3 on both sides. So multiply 2/3 times 1/2. It would equal 3. x = 3
Hope this helps. :-)
Answer:
First angle = 30°
Second angle = 60°
Third angle = 90°
Step-by-step explanation:
x + y + z = 180
y + z = 5x
z = y + 30
then:
y + (y+30) = 5x
2y + 30 = 5x
x = (2y+30)/5
then:
x + y + z = 180
{(2y+30)/5} + y + y+30 = 180
{(2y+30)/5} + 2y + 30 = 180
{(2y+30)/5} = 180 - 30 - 2y
{(2y+30)/5} = 150 - 2y
2y+30 = 5(150-2y)
2y+30 = 5*150 + 5*-2y
2y+30 = 750 - 10y
2y + 10y = 750 - 30
12y = 720
y = 720/12
y = 60°
x = (2y+30)/5
x = (2*60 + 30)/5
x = (120+30)/5
x = 150/5
x = 30°
z = y + 30
z = 60 + 30
z = 90°
Check:
x + y + z = 180°
30° + 60° + 90° = 180°
7(p)
p=3
7(3)
the answer is 21.
You got that correct it is B. here is why:
it is an obtuse because it all adds up to 180 degrees
The coordinates of the point on the directed line segment is (5,-4)
<h3>What is a line segment?</h3>
A line segment is a line drawn to join two given points on the cartesian plane.
Analysis:
x coordinate = MX1 + NY1/M + N
y coordinate = MY1 + NY1/ M+N
where M and N are the ratio of division
x = 1(-1) + 2(8)/1+2 = 15/3 = 5
y = 1(-6) + 2(-3)/1+2 = -12/3 = -4
(5,-4)
In conclusion, the coordinates are (5,-4)
