Answer:

"77 degrees"

Step-by-step explanation:

If you read the questions carefully, you will see that ∠2 and ∠4 are opposite angles to each other, or vertical angles.

We know that vertical angles are EQUAL to each other.

Hence,

∠4 = ∠2  [which is 77]

So, ∠4 = 77°

Neko [114]

Given:

The dimensions:

Square pyramid

Square base: 2x2

1 out of 4 triangles: 1/2x2x5

4 triangles: 2x2x5

To find:

The SURFACE AREA of the square pyramid

Find answer:

Step 1

Find the area of the square base -

Square base:

SA = L x W

= 2 x 2

= 4

<em>The surface area of the square is 4 square inches</em>

<em></em>

Step 2

Find the area of the 4 Triangles:

We will use a different formula here, to find 1 triangle, we will have to do:

SA = \frac{1}{2} *B*H

To find 2 triangles, we will do:

SA = B*H

But to find 4 triangles in just 1 step, we will do:

SA=2*B*H

Let's do it!

SA = 2*2*5\\=2*10\\=20

<em>The surface area of the 4 triangles are 20 square inches</em>

<em></em>

Step 3

Add answers to get FINAL ANSWER

Easy!

20+4=24

<h2>Hence, the Surface Area of the Square Pyramid is 24 square inches</h2>

<em></em>

Any negative (when there is only one of them) will be the least. negatives are smaller than positives.

A fraction is less than a whole number. So far what you have is

___ ___ 3/15 , - 24/30

So now which is bigger? 11 or 11.5

Which would you rather have? 11 dollars or 11 dollars and 50 cents. 11.5>11

The correct order is 11.5    11    3/15   - 24/30

Maru [420]

Answer:

-8  -6   -3   4

Step-by-step explanation:

In a number line, the numbers on the are lesser than the numbers on the right. In a number line with integers, numbers going to the right from the midline which is 0 is positive and increases as you move to the right. As you move to the left, the numbers are negative and decreases as you move further to the left.

Attached is a picture of how it would look on a number line.
