Answer:
x=81 degrees z=99 degrees y=68 degrees
Step-by-step explanation:
first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180) so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees
Step-by-step explanation:
(t+4)(t+7)-54=0
t²+7t+4t+28-54=0
t²+11t-26=0
(t-2)(t+13)=0
t-2=0
t=2
t+13=0
t=-13
C=15x + 150
R=45x
------
Solve:: C = R
15x + 150 = 45x
30x = 150
x = 5
---
The R = C = 45*5 = 225
