Answer:
11
Step-by-step explanation:
Use the property that angles sum up to 360 degrees.
Also use property that <M = <R and <A = <P.
That gives the following equation:
m<R + m<A + m<M + m<P = 360
6x+5 + 9x+25 + 6x+5 + 9x+25 = 360
30x + 60 = 360
x = 10
Answer:
x = 10
m<M = 6x+5 = 65 degrees
Answer: 0
Step-by-step explanation: 18a + 3 = 3
-3 -3
--------------
18a = 0 you can't divide 18 and zero it would be 0
Answer:
x = 150°
Step-by-step explanation:
The given parameters are;
AB ║ DC
∠BAE = 105°
∠AEC = 25°
We construct a line CF from C parallel to the line AE as presented in the included diagram created with Microsoft Visio
We have;
∠DCF ≅ ∠BAE = 105° by similar angles formed by two pairs of parallel lines
∠AEC = ∠ECF = 25° by alternate interior angles formed by two parallel lines and a common transversal
x = 125° + 25° = 150° By angle addition postulate
x = 150°.
