Answer:

Therefore,

$v=9\ meter$

Step-by-step explanation:

Given:

GF = 12

GE = 16

DF = 12

CF = v

To Find:

v = ?

Solution:

In Δ GFC and Δ GED

∠ E ≅ ∠ F …………..{ measure of each angle is 90° given }

∠ G ≅ ∠ G ……….....{Reflexive Property}

Δ GFC ~ Δ GED ….{Angle-Angle Similarity test}

If two triangles are similar then their sides are in proportion.

$\frac{GF}{GE} =\frac{FC}{ED} =\frac{GC}{GD}\ \textrm{corresponding sides of similar triangles are in proportion}\\$

On substituting the given values we get

$\frac{12}{16} =\frac{v}{12}\\\\v=\frac{144}{16}=9\\\\\therefore v=9\ meter$

Therefore,

$v=9\ meter$

Pls pls pls pls pls help

Arturiano [62]

Answer:

$y=\frac{1}{2}$

Step-by-step explanation:

$4(y+1)= \frac{3}{1-y}$

$4y+4= \frac{3}{1-y}$

$(4y+4)(1-y)= 3$

$4y(1-y)+4(1-y)=3$

$4y-4y^{2} +4-4y=3$

$-4y^{2}=3-4$

$4y^{2}=1$

$y^{2} = \frac{1}{4}$

$y=\sqrt{\frac{1}{4} }$

$y=\frac{1}{2}$

-1 Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).
Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:
20
+
5
=
25
So the second play they get sacked deep and lose 6 yards. So we subtract 6:
25
−
6
=
19
So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:
19
−
20
=
−
1
and this makes sense because we know we advanced 5 and fell back 6
