In a triangle, the three interior angles always add to 180°

5x + 7x + 8x = 180
20x = 180
x = 180/20
x = 9

m∠1 = 5x = 5*9 = 45°

m∠2 = 7x = 7*9 = 63°

m∠3 = 8x = 8*9 = 72°

Answer:
45°, 63° and 72°

17% of what number is 3.4
saw5 [17]

Answer:

20

Step-by-step explanation:

We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

Step 1 ---> 3.4 = 17% × Y

Step 2 ---> 3.4 = 17/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:

Step 3 ---> Y = 3.4 × 100/17

Step 4 ---> Y = 3.4 × 100 ÷ 17

Step 5 ---> Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

<h3><u>*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*</u></h3>

The new perimeter will be 3 times the old perimeter.

Original perimeter:
2(8+7) = 2(15) = 30 yds

New perimeter once they are tripled:
3 x 8 = 24
3 x 7 = 21
2(24+21) = 2(45) = 90 yds

30 x 3 = 90
