Answer:
Step-by-step explanation:
b + 70 = 180 {Supplementary angles}
b = 180 - 70
b = 110
a +b = 180 {Linear pair}
a + 110 = 180
a = 180 - 110
a = 70
d + 60 = 180 {linear pair}
d = 180 - 60
d = 120
c + d + 60 = 360 {one point angle}
c + 120 + 60 = 360
c + 180 = 360
c = 360 - 180
c = 180
f + 60 = 180 {Supplementary angles}
f = 180 - 60
f = 120
Answer:
x = 25
y = 21
Step-by-step explanation:
4x + 10 + 3x - 5 = 180° because these two angles makes a straight line
7x + 5 = 180° subtract 5 from both sides
7x = 175° divide by 7
x = 25
2y + 28 + 4y + 26 = 180° because the sum of these angles is equal to a straight line's measure
6y + 54 = 180° subtract 54 from both sides
6y = 126 divide both sides by 6
y = 21
Answer:
17.5
Step-by-step explanation:
Since the 6 behind the number being rounded is 5 or above, then you round up. If it was 4 or below you wouldn't.
Hope it helps!
It is 30. The square root of 900 is 30.
Answer:
q=12
Step-by-step explanation:
-11=61-6q
-11-61 =-6q
-72=-6q
q=72/6
q=12
