Answer:
57
Step-by-step explanation:
180-123=57
that line the angle is on is a straight line and a straight line is 180 degrees
Answer:
Option a.) an = -4(-3)^(n-1)
Answer:
x= 2.73cm
<u>1cm : 0.6828 = 4cm : 2.73cm</u>
For the same angle we just work out 1cm first.
a^2+ b^2= c^2
0.82^2 + b^2 = 1^2 = changing to units 10
6.724 + b^2 = 10
10-6.724 = 2.276
Then x 3 and change units down by 10= 0.6828
Step-by-step explanation:
Below shows why we must convert to mm from cm
a^2+ b^2= c^2
0.82^2 + b^2 = 1^2 =
0.6724 + b^2 = 1
1 - 0.6724 = b = 0.2276
0.2276 x 3 = 0.6828 cm
