Do you mean altitude as hieght?
If so, the equation would be: A = b x h x 1/2
A = 15 x 12 x 1/2
The answer would be 90.
I may be a little rusty, but I think this is right.

Answer:

The area of triangle is 90 m²

Step-by-step explanation:

We are given a triangle whose base is 15 m and altitude is 12 m.

We need to find the area of triangle.

Formula:

\text{Area of triangle }=\dfrac{1}{2}\times \text{base}\times \text{ altitude}

where. base = 15  m

Altitude = 12 m

Put the value of base and altitude into formula.

A=\dfrac{1}{2}\times 15\times 12

A = 90 m²

Hence, The area of triangle is 90 m²

Solve equation: <br> 8n-7=-12+3n
lutik1710 [3]

To solve this problem, the first thing we have to do is regroup the terms so that we can then subtract, simplify, subtract, and finally simplify again.

But first we must know.

<h3>¿What are the equations?</h3>

Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.

<h3>We solve the problem:</h3>
  • 8n - 7 = -12 + 3n
  • 8n - 7 = 3n - 12
  • 8n - 7 - 3n = -12
  • 5n - 7 = -12
  • 5n = -12 + 7
  • 5n = -5
  • N = -1

Now we must check our results.

8n -7 = -12 + 3n

8 × - 1 - 7 = -12 + 3 × - 1

- 8 - 7 = - 12 - 3

- 15 = - 12 - 3

- 15 = - 15

So, our results are correct, the answer is n = - 1

¡Hope this helped!

Express the angle in radian measure. 60°
Strike441 [17]

Pi radians =180 degrees:

<span>That is, π rad = 180°
</span>
60° in radian measure = 60° × π / 180° 

60° × π / 180° = 1/3 π rad
= 0.33333333333π rad 
= 1.0471975512 rad
