MATH. Simplify x+7=2

HACTEHA [7]

Answer:

x=-5

Step-by-step explanation:

When finding x, we basically have to isolate the variable. By isolating the variable, usually doing the opposite operation helps it.

Addition is the opposite of Subtraction

Multiplication is the opposite of Division

Let's dive into this problem!

x+7=2

(we need to isolate x. basically we need to get rid of this 7. How do we do this? since it is added by seven, we can subtract it by both sides to get rid of it on the x side.)

x+7=2

-7 -7

x=-5

(subtract 2-(-5), this adds to -5)

This is your final answer.

Answer: See Explanation

Step-by-step explanation:

This worksheet seems to be about "Special Right Triangles"

In this worksheet, it instructs you to find the missing side lengths.

Explaining number 1)

Step 1) Identifying the triangle and what it means

Since the triangle in number one is a 45-45-90 triangle with the given side length of "1" on one of the legs of the triangle, it can be concluded that the other leg also has a side length of "1" (due to the ratio of side on a 45-45-90 degree triangle), is also states the triangle has 45 degrees labeled on one of the angles, is can also be concluded that the other missing angle is 45 degrees.

Step 2) Answer

The answer to b is 1 and the answer to a is square root of 2, due to the properties of a 45 45 90 triangle (refer attachment)
