We are given that:
5[2p-4(p+5)]=25
<span> First thing to do is to divide everything by 5 so that:</span>
2p-4(p+5)=5
Then distribute -4:
2p – 4p – 20 = 5
Combine like terms:
-2p = 5 + 20
-2p = 25
<span>p = -12.5</span>
One radius is 4m and other one is 8m
Answer:
126°
Step-by-step explanation:
the internal sum of the angles is always 180
28+26= 54
180-54= 126
17
y=4(3)+5
y=12+5
y=17
