Answer:
80
Step-by-step explanation:
20 x 4 = 80
Answer: 14 meters
Step-by-step explanation:
Use the pythagorean theorem to solve.
12 ² + 8 ²= c ²
208= c ²
√ 208 = √ c ²
14.42= c
14 meters
Answer:
The difference is 40,
Step-by-step explanation:
Complementary angles , x+y =90
so we know angle 1, we call it 3x and angle 2 we call it y= 3x+10
so 3x +10= 90-x
4x=100
x=25
angle 1= 3(25) - 10
y= 65
65-25= 40
-4 is the correct answer
35-12 =25
-4 - ( -27) = -4 + 27 =23
The modulus of complex number can be computed with this equation:
|z|=sqrt(Re(z)^2+Im(z)^2)
z = -2-6i
Re(z)=-2, so Re(z)^2=4
Im(z)=-6, so Im(z)^2=36
|z|=sqrt(36+4)=sqrt(40)=6.3
