Given : (8 + i)(2 + 7i)
⇒ (8 × 2) + (8 × 7i) + (i × 2) + (i × 7i)
⇒ 16 + 56i + 2i + 7i²
We know that i² = -1
⇒ 16 + 58i + 7(-1)
⇒ 16 + 58i - 7
⇒ 9 + 58i
Answer:
Question #1 choice A x=3, ST=24 and Question #2 choice C x =12
Step-by-step explanation:
Question #1
T midpoint so ST=TU and 8x = 2x+18
8x =2x+18
8x-2x=18
6x=18
x=18/6
x=3
so ST= 8x=8*3=24
choice A
Question #2
M midpoint of AB so AM=MB and 4x+1=7x-35
4x+1=7x-35
1+35=7x-4x
36=3x
36/3=x
12=x
choice C
Answer:
40°
Step-by-step explanation:
180-(57+43)=100°
which mean the angle at the top =100°
180-100=80°
x=80/2
x=40
