Answer:
x = 26
y = 9
Step-by-step explanation:
(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)
Solve for x
5x - 17 + 3x - 11 = 180
Collect like terms
5x + 3x - 17 - 11 = 180
8x - 28 = 180
Add 28 to both sides
8x = 180 + 28
8x = 208
Divide both sides by 8
x = 208/8
x = 26
Also:
(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)
Plug in the value of x and solve for y
2y + 5 + 90 + 3(26) - 11 = 180
2y + 5 + 90 + 78 - 11 = 180
Collect like terms
2y + 162 = 180
Subtract 162 from both sides
2y = 180 - 162
2y = 18
y = 9 (dividing both sides by 2)
Answer:
20 is not a coefficient
True - constants are numbers that donʻt have a varible
Step-by-step explanation:
I hope this helps stay safe and have a good day! Can i get a brainiest if correct?
So let's say that the second angle is x.
Then we can say that the third angle is
.
So then we have three angles:
1) 66°
2) x°
3) (
)°
So then we can add these together and solve for x by setting it equal to the total degrees left in the triangle after subtracting the known angle:





So now we know that the measure of the second angle is 38°. So then we can use this value to solve for the third angle:

So the values of the angles are:
1) 66°
2) 38°
3) 76°
Answer:
the answer is E. none of the above
X=(6-2)+2
X=4+2
X=6
y=(4-6)+6
y=-2+6
y=4
coordinates of point T are 6,4
