I have to find the angle measurements of a interior triangle a is 4x b is 7x-2 and c is 5x-10

RSB [31]

Answer:

$m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o$

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle a+m\angle b+m\angle c=180^o$

substitute the given values

$4x^o+(7x-2)^o+(5x-10)^o=180^o$

solve for x

$(16x-12)^o=180^o$

$16x=180+12\\16x=192\\x=12$

Find the angle measurements

$m\angle a=4(12)=48^o$

$m\angle b=7(12)-2=82^o$

$m\angle c=5(12)-10)=50^o$

Help me pls i really dk

I think its easier to work out part (c) first:-

People who liked anything except burger = 3/8 + 1/4 + 1/5 = 33/40

So the fraction who liked burgers = 7/40.

7/40 of the total liked burgers so total people surveyed = (40/7) * 126 = 720

ANswer to c is 720.

a) Number who liked chicken and laksa = (3/8 + 1/4) * 720 = 450 Answer

b) Number who liked pasta = 1/5 * 720 = 144

Therefore 144-126 = 18 more people liked pasta than burger , Answer.
