Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
-3(x+y)=-3(19)
---------------------
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
165
c = 6 and d = 10
= 5 × 6² = 5 × 36 = 180
- ( 3 d ) = 180 - ( 3 × 10 ) = 180 - 30 = 150
- 3 d ( + 15 ) = 150 + 15 = 165
15.01
7×tan65=15.01 hopefully this help
c
the answer is c becuase on the height
B
