Answer:

B = 48

Step-by-step explanation:

Complementary angles add to 90

A+B = 90

42+B = 90

Subtract 42 from each side

B = 90-42

B = 48

Answer:

\Huge \boxed{\angle B = 48 \° }

\rule[225]{225}{2}

Step-by-step explanation:

Two angles are complementary when they add up to 90 degrees.

\angle A + \angle B = 90

\angle B = 90 - \angle A

\angle B = 90 - 42

Subtracting the values,

\angle B = 48

\rule[225]{225}{2}

The diameter of Jupiter is 142.984 Km. The surface area of Saturn is 59.9% the surface area of Jupiter. What is Saturn's diamete
Otrada [13]
Suppose that both planets are spherical. radius of Saturn =142984/2=71,492

Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10

Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10

Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km

The sides of an isosceles triangle are 8, 8, and 3. The measure of the vertex angle to the nearest degree is _____°. 44 17 31 22
Doss [256]
We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5

We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°

This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°

The number of employees per department are normally distributed with a population standard deviation of 198 employees and an unk
cricket20 [7]

Answer:

EBM = +-54.126

Step-by-step explanation:

In this question we have confidence interval to be 80%

The formula to solve this is in the attachment.

Bar X = 1460

Z-alpha/2 = 1.282

Sd = standard deviation = 198 employees

n = 22 departments

After we have inserted all values in to the formula we have:

1460 +-(1.282*198/√22)

= 1460+-(54.12604)

= (1405.87, 1514.126)

The error bounded mean EBM

= +-z-alpha/2 x (sd/√n)

= 1.282 x 198/√22

= 1.282 x 42.22

EBM = +-54.126
