Answer:

1122

If you do 18 (the first number in the sequence) plus 69 because you have to do 70 minus 1 equals 69. So 18 plus 69 then you times 16 (how many you have to get to the next number).

18+69×16=1122

Find the total surface area of the cuboid

vivado [14]

Answer:

A = 148 cm^2

Step-by-step explanation:

To calculate the surface area of the cuboid we use the following equation

A = 2 x (lh + lw+ hw) (l: length, w: width, h: height)

A = 2 x (6*5 + 6*4 + 5*4)

A = 2 x (30 + 24 + 20)

A = 2 x 74

A = 148 cm^2

In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?

Andreas93 [3]

Given:

Consider the below figure attached with this question.

$m\angle 3=(x+30)^\circ$ and $m\angle 4=(2x-80)^\circ$ .

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

$m\angle 3=m\angle 4$

$(x+30)^\circ=(2x-80)^\circ$

$x+30=2x-80$

$x-2x=-30-80$

$-x=-110$

$x=110$

Now,

$m\angle 3=(110+30)^\circ$

$m\angle 3=140^\circ$

Therefore, the measure of angle 3 is 140 degrees.
