Supplementary angles are angles whose sum is equal to 180°.
Let one angle be x
The other angle is said to be 26°more than the other so it is x + 26
x + (x+26) = 180
x + x + 26 = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77
1st angle, x, is equal to 77°
2nd angle, x + 26°, is 77° + 26° = 103°
77° + 103° = 180°
180° = 180°
Answer:
32 cm
Step-by-step explanation:
The original height is 40. - Given
20 percent is also equal to 1/5
SO the expression would be 1/5 x 40 cm
You get 8 cm.
Then, you subtract 8 from 40 to get 32 cm.
Answer:
3/7
Step-by-step explanation:
you are gonna add all the parts together which is seven and because three parts are blue chances are that it might stop at blue three times out of seven
1.
a. -10/7
b. 5/3
c. 3.02
d. 6 1/2 (it is a bit blury, hard to tell)
explanation- so the opposite of a positive is a negative, the opposite of a negative is a positive. so it is the same for this. for example 10/7 is positive so you make it a negative for it be the opposite.
i would help with the rest, but it is hard when you have to label things on a diagram when you are doing it on a computer like this. sorry!
Answer:
-3x-2y
Step-by-step explanation:
(-6x+3y)-(-3x+5y)
-6x+3x+3y-5y
-3x-2y
