Solve for j. please help meee
Answer:
112 degrees
Step-by-step explanation:
Angle J and the other angle combines to form a straight angle. In other words, they must total 180 degrees. Thus:
[tex]68+j=180[/tex]
Subtract 68 from both sides:
[tex]j=112\textdegree[/tex]
And we're done!
Answer:
I believe the answer is 112 degrees
Step-by-step explanation:
If you know, a straight line hs 180 degrees. Well, then having this knowledge, make a simple equation x+68=180.
Then Solve the equation
x+68=180
-68 -68
x=112

subtract -9x-7 from 8x2 -5x +9
Answer:
8x2+4x+16
Step-by-step explanation:
first you would place as so
8x2-5x+9 - (-9x-7)
you would then change question to addition but do this you would have to switch the signs for the one in the parenthisis. it would look like 8x2-5x+9 + 9x+7
You then add like terms and put them into standard form.
hope this helps!!

A ramp is 35 ft long rises to a platform. The bottom is 15 ft from the foot of the ramp. Find x, the angle of elevation of the ramp. Round your answer to the nearest tenth of a degree.
Answer:
The angle of elevation of the ramp is 64.60°
Step-by-step explanation:
Given;
length of the ramp, L = 35 ft
distance of the platform to the foot of the ramp, d = 15 ft
The length of the ramp forms the hypotenuse side of this right angled triangle;
The angle of elevation of the ramp is in angle between the hypotenuse and adjacent side of the triangle.
Cos x = adjacent / hypotenuse
Cos x = 15 / 35
Cos x = 0.4286
x = Cos⁻¹ (0.4286)
x = 64.62
x = 64.60°
Therefore, the angle of elevation of the ramp is 64.60°
Point T is on line segment \overline{SU} SU . Given TU=4x+1,TU=4x+1, SU=8,SU=8, and ST=3x,ST=3x, determine the numerical length of \overline{TU}. TU .
Answer:
5Step-by-step explanation:
If point T is on the line SU, then ST+TU = SU. Given TU=4x+1, SU=8, and ST=3x
Substituting the given values into the expression ST+TU = SU
8 = 3x+4x+1
8 = 7x+1
collect like terms;
7x = 8-1
7x = 7
Divide through by 7
7x/7 = 7/7
x = 1
Substitute x = 1 into the expression TU = 4x+1 to get the length of TU
TU = 4(1)+1
TU = 4+1
TU = 5
Hence the length of TU is 5
Answer:
Step-by-step explanation: the answer is 5
For each pair of polygons, describe a sequence of translations, rotations, and reflections that takes Polygon P to Polygon Q.
Answer:
1. It is a reflection across the y axis, a rotation and a translation to the right and down.
2. A reflection across the x-axis, translation left 2 and down 1, with a 45 degree clockwise rotation.
3. An 180 degree reflection on line bc and a translation
Step-by-step explanation:
Case 1 involves translation and rotation.
Case 2 involves translation, rotation and reflection.
Case 3 involves translation and reflection.
In this question, we are going to describe succinctly all Steps needed to turn each Polygon P into respective Polygon Q:
Case 1:
(i) Translation along a Vector between Points A and H.
(ii) Rotation around Point H.
Case 2:
(i) Translation along a Vector between Points B and J.
(ii) Rotation around Point J.
(iii) Reflection with respect to a "vertical" Lines passing through Point J.
Case 3:
(i) Translation along a Vector between Points B and F.
(ii) Reflection with respect to a Line passing through Segment FD.

To find:
The number of possible solutions, if the Order of Operations did not exist.
Solution:
We have,
[tex]4 + 9 + 16 \div 4 - 8 -3 \times 5[/tex]
Now,
Case 1:

[tex]4 + 9 + 16 \div (4 - 8 -3) \times 5=-\dfrac{29}{35}[/tex]
Case 3:
[tex]4 + 9 + (16 \div 4) - 8 -(3 \times 5)=4+9+4-8-15[/tex]
