Answer:
c) j=2 and h=4
Step-by-step explanation:
h+h+j+4+j+4=20
3h+3h+j+1+j+1=30
2h+2j+8=20
6h+2j+2=30
multiply the first equation by -3
-6h-6j-24=-60
this equals
-6h-6j=-36
6h+2j=28
-4j=-8
j=2
Since j=2
2h+2(2)+8=20
2h+12=20
2h=8
h=4
Answer:
7. 130 + 150 = 280
360 - 280 = 80 degrees
Step-by-step explanation:
It is a pattern so 2*3=6
3 times 4 is 12
4 times 5 is 20
5 times 6 is 30
6 times 7 is 42
so, 9 times 8 is 72.

Answer:
Step-by-step explanation:
label sides adjacent h and o
sin(30) times 12 = 6 = 10
