first we need to find x.
and then we can calculate the area by
baseline × height / 2
which is here
12 × x / 2
x we get via Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
15² = 12² + x²
x² = 15² - 12² = 225 - 144 = 81
x = 9
the area of the triangle is then
12 × 9 / 2 = 6×9 = 54 m²
- perpendicular side= 12m
- hypotheses side= 15m
- base = x m
- Pythagoras theorem h²= p²+b²
- and area of traingle = 1/2xbxh
∵h²= p²+b²
➡(15)²=(12)²+ x²
➡x²= (15)²-(12)²
➡x²= 225-144= 81m
➡x=√81= 9m
☆ area of traingle:-
∵hence ,area of traingle is 54 cm²

Answer:
Square
Explanation:
A square is the only other shape with 4 right angles
Answer:
i think its C but not sure
Step-by-step explanation:
-2x + 12 = 2y
Add 2x on both sides,
12 = 2y + 2x
Divide by 2 on both sides,
6 = y + x -> x + y = 6
The answer is D.
It depends on the value of t.
X= -5/2 + 1/2 square of 33 or x= -5/2 + -1/2 square root of 33
