Answer:
11
Step-by-step explanation:
Dot product is
a*b = |a|*|b|*cosα.
In our case
u*u =|u|*|u|*cos 0
u*u =|u|*|u|
12=|u|²
|u|=√12=√(4*3)=2√3
Answer: <span>D. 2√3</span>
A=34°
B=76°
C and d = 70°
because a triangle is 180° and we know
a+b+c=180
76+34=110
180-110=70
12 = 15 (z - 1/5)
12 = 15z - 3
+3 +3
15 = 15z
15 (÷ 15) = 15z (÷ 15)
1 = z
Hope I helped!!! :)
