11.5/25=theta
theta=.46
Answer:
x=81
y=99
z= 129
Step-by-step explanation:
the 3 angles of a triangle add to 180 degrees
51 + 48 + x = 180
99 + x = 180
subtract 99 from each side
99 + x -99 = 180 -99
x = 81
x+y = 180 they make a straight line
81+ y = 180
subtract 81 from each side
y = 180-81
y = 99
z+ 51 = 180 they make a straight line
subtract 51 from each side
z+51-51 = 180 -51
z = 129
Answer:
It looks like on step c he took away 10 instead of adding 10
Answer:
d. 11
Step-by-step explanation:
<u>Ratio of corresponding sides:</u>
- x/12.2 = 4.6/5.1
- x = 12.2*4.6/5.1
- x = 11
Correct option is d. 11
