The value of y in the triangle is 7.5

<h3>How to calculate the value of y?</h3>

The given parameter is the triangle

On the triangle, we have the following equivalent ratio

y : 8 = y + 15 : 20

Express as fraction

y/8 = y + 15/20

Cross multiply

20y = 8y + 90

Collect the like terms

20y - 8y = 90

Evaluate

12y = 90

Divide by 12

y = 7.5

Hence, the value of y in the triangle is 7.5

19.2 * 10⁸ minutes = (19.2 * 10⁸) / 60 hour

= 32 000 000 = 3.2 * 10⁷ hours

$a+b+c=180, \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\$

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.

Solve for 2/5 + 3/8= With two possible answeres

Pani-rosa [81]

You can change the denominators so they are alike. $\frac{16}{40} + \frac{15}{40} = \frac{31}{40}$
Not sure how there can be two possible answers unless you're mentioning the decimal form:
.775
Tell me if this helps!!
