Answer:

H_B=169.2m

Step-by-step explanation:

From the question we are told that:

Average height of blocks H_{ABC}=145.6

Height of block A H_A=128.7

Height of block C H_C=138.9

Generally the equation for Height of block C is mathematically given by

Since

H_{ABC}=\frac{H_A+H_B+H_C}{3}

Therefore

H_B=(H_{ABC}*3)-(H_A+H_B)

H_B=(145.6*3)-(128.7+138.9)

H_B=169.2m

What is the value of the angle marked with xxx?
natali 33 [55]

Answer:

Here you go!! :)

Step-by-step explanation:

Given that the sides of the quadrilateral are 3.3

The measure of one angle is 116°

We need to determine the value of x.

<u>Value of x:</u>

Since, the given quadrilateral is a rhombus because it has all four sides equal.

We know the property that the opposite sides of the rhombus are equal.

The measure of the opposite angle is 116°

x = measure of opposite angle

x = 116°

Then, the value of x is 116°

Therefore,<u><em> the value of x is 116°</em></u>
