Answer:

X = 474

Step-by-step explanation:

2x-16 x 60 = -12

2x - 960 = -12

2x - 960= -12

2x -12 + 960

2x= 948

X= 948/2

X= 474

Please help (angles)​
OLEGan [10]
Angle 6&5 are supplementary so they make a line. (Add to 180.)
(3x-34)+124=180 combine like terms
3x + 90=180 subtract 90 from both sides
3x = 90. Divide by 3
X = 30

Find the value of angle x , angle y, and angle z in figure.​
Lynna [10]

\bf \underline{★ Solution-} \\

In the given figure, we are given with two lines which are parallel to each other. We are also given with two lines which forms a triangle and also forms as a transversal lines to the parallel lines. We are also given that the given triangle is an isosceles triangle. So, we can say that the other angle in the triangle also measures 75°.

Now, let's find the value of the ∠x.

We know that the alternate angles in the parallel line always measures the same as the one which is in it's alternate side. So,

\sf \leadsto \angle{x} = {75}^{\circ}

Now, let's find the value of the ∠z.

We know that, all the angles in a triangle always adds up to 180°. In the given triangle, we are given with two angles, so we can easily find the third angle.

\sf \leadsto {75}^{\circ} + {75}^{\circ} + \angle{z} = {180}^{\circ}

\sf \leadsto {150}^{\circ} + \angle{z} = {180}^{\circ}

\sf \leadsto \angle{z} = 180 - 150

\sf \leadsto \angle{z} = {30}^{\circ}

Now, let's find the value of the ∠y.

We know that all the angles that forms a straight line always equals up to 180° (or) the the straight line angle always measures 180°. So, we can find the value of the ∠y by this concept.

\sf \leadsto {75}^{\circ} + {30}^{\circ} + \angle{y} = {180}^{\circ}

\sf \leadsto {105}^{\circ} + \angle{y} = {180}^{\circ}

\sf \dashrightarrow \angle{y} = 180 - 105

\sf \dashrightarrow \angle{y} = {75}^{\circ}

Therefore,

  1. The value of the ∠x is 75°.
  2. The value of the ∠y is 75°.
  3. The value of the ∠z is 30°.

A person who is 64 inches tall has a shoulder width of 16 inches. Write an equation relating the height h to the width w. Find t
kicyunya [14]

Let the height of the person with shoulder width of 18.5 be = x

As given, A person who is 64 inches tall has a shoulder width of 16 inches.

So, we have to find the height when the shoulder width is 18.5 inches.

We can relate these two by ;

\frac{64}{16}=\frac{x}{18.5}

16x=64*18.5

16x=1184

x=74

Hence, the height of the person should be 74 inches.
