4(2x-5)+15=11
8x-20+15=11
8x-5=11
8x=11+5
8x=16
x=16/8
x=2
Hope it helps

If the pattern shown continues, how many black keys appear on a pipe organ with a total of 120 keys? Suggestion: use equivalent

irga5000 [103]

in 12 key 5 black keys are appearing so consider x key will appear in 120 keys

120/x = 12/5

solving further,

x= 50

Answer - If the pattern shown continues, 50 black keys appear on a pipe organ with a total of 120 keys!

Suppose that ABCD is isosceles with base BC.

nika2105 [10]

It is an isosceles triangle which means that side BD=BC, The angles will be also equal i.e. Angle B= Angle C

<h3>Now,</h3>

Angle B = 4x+19
Angle C = 2x+33

$4x + 19 = 2x + 33$

$4x + 19 - 2x = 33$

$4x - 2x = 33 - 19$

$2x = 14$

$x = 7$

<h3>Calculating the angles:</h3>

$∠b = 4x + 19 \\ = 4 \times 7 + 19 \\ = 47$

$∠c = 2x + 33 \\ = 2 \times 7 + 33 \\ = 47$

Now, We will find ∠D with the help of angle sum property of triangle

$∠b + ∠c + ∠d = 180 \\ 47 + 47 + x = 180 \\ 94 + x = 180 \\ x =180 - 94 \\ x = 86$

<em>The measure of angles are; 47°,47°,86° respectively</em><em>.</em><em>.</em><em>.</em>
