Answer:
<QPR = 98.5 degrees
Step-by-step explanation:
a line = 180 degrees
7x + 4 + 9x - 40 = 180
16x - 36 = 180
16x = 216
x = 13.5
<QPR = 7x + 4 = 7(13.5) + 4 = 98.5
Answer:
1/10 x 58 =5.8 if they want it in fraction its 4/5
The image of the diagram is missing, so i have attached it.
Answer:
a = 30°
Step-by-step explanation:
From the diagram attached, we can see that the 2 angles a and 5a are interior supplementary angles.
The sum of interior supplementary angles is 180°
Thus;
5a + a = 180
6a = 180
a = 180/6
a = 30°
