Can someone please help with #16

Answer:

∠ WZX = 50°

XW is not an altitude.

Step-by-step explanation:

16. See the attached figure.

XW is the angle bisector of ∠ YXZ, hence, ∠ WXY = ∠ WXZ

Now, given that ∠ YXZ = 8x + 34 and ∠ WXY = 10x - 13

Hence, ∠ YXZ = 2 ∠ WXY

⇒ 8x + 34 = 2(10x - 13)

⇒ 8x + 34 = 20x - 26

⇒ 12x = 60

⇒ x = 5.

Hence, ∠ XZY = ∠ WZX = 10x = 50° (Answer)

Now, ∠ WXZ = ∠ WXY = 10x - 13 = 37°

Hence, from Δ WXZ,

∠ WZX + ∠ WXZ + ∠ XWZ = 180°

⇒ 50° + 37° + ∠ XWZ = 180°

⇒ ∠ XWZ = 93° ≠ 90°

Hence, XW is not an altitude. (Answer)

5/16t=-9

Svetradugi [14.3K]

I'm going to assume that the equation is $\frac{5}{16}t = -9$ where the 't' is not in the denominator

If that assumption is correct, then we do two things to solve for t. First, we multiply both sides by 16. This undoes the division of 16 on the left side

$\frac{5}{16}t = -9$

$16*\frac{5}{16}t = 16*(-9)$

$5t = -144$

-------------------------------

Then we divide both sides by 5 to undo the multiplication of 5 (note: 5t means 5*t or "5 times t")

$5t = -144$

$\frac{5t}{5} = \frac{-144}{5}$

$t = -\frac{144}{5}$

-------------------------------

So here's what all the steps look like:

$\frac{5}{16}t = -9$

$16*\frac{5}{16}t = 16*(-9)$

$5t = -144$

$\frac{5t}{5} = \frac{-144}{5}$

$t = -\frac{144}{5}$

note: -144/5 converts to the decimal value of -28.8 so t = -144/5 is the same as t = -28.8

How many times smaller is the value of the 6 in 621 than the value of the 6 in 6420

SashulF [63]

The 6 in 621 is in the hundred's place, so alone it would equal 600.

However, the 6 in 6,420 is in the thousand's place, so it alone would equal 6,000.

The question is asking how many times smaller is the value of 6 in these two numbers. Therefore, you need to divide 6,000 by 600.

Your answer should be 10.

If measure of angle abd=48 and measure of angle dbc=78 find the measure of angle abc

slega [8]

Answer:

Step-by-step explanation:

given <abd = 48 and <dbc = 78, hence the addition rule is true<abc = <abd + < dbc

Substituting the given values inti the formula;

< abc = 48+78

< abc = 126°

The measure of angle abc is therefore 126°
