Answer:

1. U. 190

2.U. 155

3. U. 240

Step-by-step explanation:

Explanation: To find an angle of a triangle we add the angles we know about

EXAMPLE: 50 + 120. We need to find the third angle.

We know that Angles of triangles should add up to 360

So to find the third angle we add the angle we know about.

EXAMPLE: 50 + 120 = 170 then we Subtract the sum of a triangle *360*

EXAMPLE: 50 + 120 = 170

EXAMPLE: 170 - 360

EXAMPLE: = 190

That's how we find a third angle!

If this doesn't clarify how do to it enough just let me know and i can try to explain more in detail!

Hope this helps you!!!

Have a nice day!

How do u write 1.2 as a fraction
Ivahew [28]
Split the number into its whole number component and decimal component.

for the decimal component, 0.2 is the same as 2/10

Find the GCF of both 2 and 10 and that would be 2

divide both the numerator and denominator by the GCF 

simplify and you get 1/5

Lastly combine the whole number component with the fraction and your answer would be 1 1/5.

CAN SOMEONE JUST PLEASE ANSWER THIS ASAP FOR BRAINLIEST!!’
sesenic [268]
ANSWER

The three expressions are

V = 2(9 - {b}^{3} )(9 + {b}^{3} )

EXPLANATION

We were given the volume in cubic units to

V = 162 - 2 {b}^{6}

If we factor 2, we get,

V = 2(81 - {b}^{6} )

The expression in parenthesis is a difference of two squares. But you may not recognize it at first sight.

V = 2( {9}^{2} - ({b}^{3})^{2} )

This further gives us.

V = (2)(9 - {b}^{3} )(9 + {b}^{3} )

What is -4d 3 + 28d 2 - 4d
Svetlanka [38]

Answer: 20d + 5

Step-by-step explanation:

First we need to combine like terms.

In this equation we can see that they're are 3 numbers containing the letter D we have -4, -4, 28.

We're going to combine -4 and -4 to get -8 and then combine -8 to 28 getting 20d

Afterwards we're going to combine 3, 2 equaling 5.

John joined a video game club. Newer games cost $5 to rent and older games cost $3 to rent John has $30 to spend each month. How
LUCKY_DIMON [66]

Answer:

6 newer games and 10 older games

Step-by-step explanation:

To find how many newer games John can purchase, we divide $30 by $5. If we do the simple math in our head, we will get the answer of 6. Therefore, the amount of newer games John can purchase is 6. Now to find the amount of older games John can buy, we apply the same strategy. We take $30 and we divide it by $3. This will get us the answer of 10. Therefore, the amount of older games John can purchase is 10.

Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time and good luck finding the correct answer :)
