Answer:
a = 38 degree
b = 54 degree
c = 54 degree
Step-by-step explanation:
a = 180 - 142 = 38 ( angle on a straight line is equal to 180)
To determine the value of b, we have to find the other missing angle in the triangle.
the value of the missing angle is 38
Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38
b = 180 - (38 + 88) = 54
c = 54
1425/100=(57•25)/(4•25)
=57/4
=14 1/4
Answer:
how the heck would I know what she's buying the question itself doesn't even state that
The answer is 1/2. if you do 15/124 x 230/30 it equals 115/124. then divide that by 230/124 with give you 1/2
Answer:
39°
Step-by-step explanation:
<u>Internal angles of the triangle are: </u>
<u>Angle x is:</u>
- x = 180° - (60° + 81°)
- x = 180° - 141°
- x = 39°
