I think 180 is supplementary angle
Answer:
1.you don't need to calculate 25²,7²,30² and 16² because you have a formula a²-b²=(a+b)(a-b)
OP²=MO²-MP²
OP²=25²-7²
OP²=(25+7)(25-7)
=32(8)
=256
OP=√256
OP=16 cm
NP²=NO²-OP²
NP²=30²-16²
=(30+16)(30-16)
=46(14)
=144
NP=√144
=12 cm
2.draw a straight line from the angle C and name that line with CE
CE=AD and AE=CD (because AECD is a rechtangular)
So EB=10-7 =3 cm
BC²=EC²+EB²
=4²+3²
=16+9
=25
BC=√25
=5 cm
for area of the square? i don't understand this question...
Answer: x=15
Step-by-step explanation:
subtract 8 from 18 = 10 then divide the 10 by 2/3
