ANSWER

The value of y is
5

EXPLANATION

The given triangle is isosceles.

The base angles are 75° each.

The sum of the interior angles must be 180°

This implies that,

4y + 10 + 75 + 75 =180 \degree

We simplify to get,

4y + 160 = 180

We group like terms to get,

4y = 180 - 160
This will give us,

4y = 20

We divide through by 4 to get,

y = 5

Answer:

The value of Y is 5.

Step-by-step explanation:

I am assuming you're asking of this particular question?

If so, start out by creating a theory that if both sides of the triangle are marked as "equal" with one mark, then both angles of B and C should be equal as well. So, in other words, <em>75</em> = <em>(3x)</em>. Or, in more simpler terms, 75 = 75.

With that in mind, we'll now add all angles to equal 180 since this shape is a triangle. 75 + 75 + (4y+10) = 180.

Add similar terms, 150 + (4y+10) = 180.

Subtract 150 from both sides; (4y+10) = 30.

Subtraction Property of Equality (Subtract 10 from both sides); 4y = 20.

Finally, divide both sides by 4. Y = 5.

ioda

Answer:

Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%.

Step-by-step explanation:

Given that Elena receives $ 131 per year in simple interest from three investments totaling $ 3000, and part is invested at 3%, part at 4% and part at 5%, and there is $ 1000 more invested at 5% than at 4%, to find the amount invested at each rate, the following calculations must be performed:

1500 x 0.05 + 500 x 0.04 + 1000 x 0.03 = 75 + 20 + 30 = 125

1600 x 0.05 + 600 x 0.04 + 800 x 0.03 = 80 + 24 + 24 = 128

1700 x 0.05 + 700 x 0.04 + 600 x 0.03 = 85 + 28 + 18 = 131

Therefore, Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%
