Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90
Answer:
3x2+9x+3y
Step-by-step explanation:
Let's simplify step-by-step.
17x+3x2+2y+y−5x−3x
=17x+3x2+2y+y+−5x+−3x
Combine Like Terms:
=17x+3x2+2y+y+−5x+−3x
=(3x2)+(17x+−5x+−3x)+(2y+y)
23 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
23 centimeter -> x kilometer
We clear x:
x = (23/1) * (1)
x = 23 kilometers
0.5 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
0.5 centimeter -> x kilometer
We clear x:
x = (0.5 / 1) * (1)
x = 0.5 kilometers
9 centimeters =
We make the following rule of three:
1 centimeter ----> 1 kilometer
9 centimeter -> x kilometer
We clear x:
x = (9/1) * (1)
x = 9 kilometers
Answer:
c. 23 kilometers
a. 0.5 kilometers
b. 9 kilometers
