Answer:
D.
Step-by-step explanation:
Are of the triangle= height x base/2
15.2 x 35.6
541.12/2
270.56
If you are worried about 23.4´s in the triangle they always tend to be there and confuse the student.The height will always have that little square.
Sorry I only know the answer to b.

Answer:
45°
Step-by-step explanation:
Arc YZ is the difference between the given arcs and 360°:
126° +144° +YZ = 360°
YZ = 360° -270° = 90°
The inscribed angle (?) is half the measure of the arc it intercepts:
? = 90°/2
? = 45°
Answer: The answer is x=0
Step-by-step explanation:
Rewrite the equation as a trinomial.
x
2
+
12
x
+
0
Move 0 to the right-hand side.
x
2
+
12
x
=
0
Divide the coefficient of the x
-term by 2, then square the result. Add the result to both sides.

;6^2
=

x

Factor the perfect square trinomial
x

+
12
x
+
36
on the left-hand side.
(
x
+
6
)

=

Take the square root of both sides and solve for x
.
