Which statement regarding the diagram is true?
2 answers:
1. Let the m(YXZ)=a, m(XZY)=b, m(XYZ)=c, m(WXY)=d as in the atached figure.
A) d=a,
no, because clearly the triangle is an acute triangle (all angles clearly < 90°).
So a<90, and d, the supplementary of a, is >90. So d>a
B) d<b.
no, d >90, b<90 so d>b
C) d+a=180°
yes, because an interior angle, and that angles exterior angle are supplementary, that is, their sum is 180°
D) d+c=180°. True only if c=a, so if YZX is isosceles. Otherwise, not true.

Answer:
Step-by-step explanation:
Considering the geometric sequence
As the common ratio '' between consecutive terms is constant.
The general term of a geometric sequence is given by the formula:
where is the initial term and
the common ratio.
Putting ,
and
in the general term of a geometric sequence to determine the 12th term of the sequence.
∵
Therefore,
8. first 12 bags for 54m^{2}
[/tex]
54 ÷ 12 = 4.5
we know: 1 bag for 4.5m^2
36 ÷ 4.5 = 8
so 36m^2 we must use 8 bags
9.
x2 =5x2/8= 10/8 = 5/4 = 1.25
