Answer: Triangle: x = 40 Line: x = 10

Explanation:
All angles of a triangle adds up to 180. So x + 50 + 90 (the square box represents a 90° angle) = 180
Simplify: x + 140 = 180
So x = 40°

A straight line is 180°
so 7x+110=180
7x= 70
x=10

Answer:

x = 40

x = 10

Step-by-step explanation:

Problem 1

The sum of all angle measures in any triangle is (180) degrees. In this problem, one is given that one of the angle measures is (50) another is (x) and the final is (90) degrees. A general rule is that when an angle has a box around, its degree measure is 90 degrees. One can apply this here by stating the following,

x + 50 + 90 = 180

Simplify,

x + 140 = 180

Inverse operations,

x + 140 = 180

   -140    -140

x = 40

Problem 2

The degree measure of a straight line is (180) degrees, the two given angles in this picture form a straight line. Thus, the sum of their angle measures is (180) degrees. Form an equation off of this information and solve for (x),

110 + 7x = 180

-110           -110

7x = 70

/7     /7

x = 10

Solve -2(2x+5) -3(x-1)
OLEGan [10]
<h2>Hello!</h2>

The answer is:

-2(2x+5)-3(x-1)=-7x-7\\

<h2>Why?</h2>

To solve the problem, we need to perform the operations and then, add like terms.

We need to apply the distributive property, which is defined by the following way:

a(b+c)=ab+ac

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

3x+5x+x^{2}=8x+x^{2}

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.

So, we are given the expression:

-2(2x+5)-3(x-1)

Then, solving we have:

-2(2x+5)-3(x-1)=-4x-10-(3x-3)\\\\-4x-10-(3x-3)=-4x-10-3x+3\\\\-4x-10-3x+3=-4x-3x-10+3\\\\-4x-3x-10+3=-7x-7

Hence, we have that the answer is:

-2(2x+5)-3(x-1)=-7x-7\\

Have a nice day!
