Answer:
Your answer of 10 x 12 - 14 +2+15 =123
Actually, the area of a triangle is a = bh/2. If a = 30 and b = 12:



So he height is 5 units
X = 33
The angles in a triangle must add up to 180 degrees









Therefore , the value of x = -1
Answer:
Subtract 3 from both sides.
Step-by-step explanation:
x + 3 = 5
x = 5 - 3
<u>x = 2</u>
I know I`m late sorry, still wanted to answer
