G(3)=2(3)+5

g(3)= 6 + 5

g(3)= 11

your point is (3, 11).

**Answer:**

**Step-by-step explanation:**

<u>Area formula for equilateral triangle with side a:</u>

<u>The base area is:</u>

The three lateral surfaces have same sides of 10, 10 and 12.

<u>Find each surface area using heron's formula:</u>

- s = P/2 = (10 + 10 + 12)/2 = 16
- s - a = 16 - 10 = 6
- s - b = 6
- s - c = 16 - 12 = 4

<u>Total surface area is:</u>

**Correct choice is C**

**Answer:**

90

**Step-by-step explanation:**

Alright first step what is the degree measure of LN.

A full rotation is 360 degrees so LN=360-270=90.

So angle M is half the difference of the intercepted arcs:
