Answer 1

Answer:

1. 5x+1x=180

6x=180

x=180/6

x=30

angle 1=5×30=150 degrees

angle 2=1×30=30 degrees

2. 8x-5x=72

3x=72

x=72/3

x=24kg

Answer 2

Step-by-step explanation:

:

1)The ratio of two supplementary angles=5:1

Let they be 5x and x

Their sum =5x+x =6x

We know thatThe sum of two angles is 180° they are supplementary Angles

=>6x=180°

=>x=180°/6

=>x=30°

=>5x=5(30)=150°

The measurements of the given angles are 150° and 30°

2)Ratio of a man reduces his weight =8:5

Let his weight be 8x

and reduces weight be 5x

his original weight=72 kg

=>8x=72

=>x=72/8

=>x=9kg

=5x=5(9)=45 kg

weight of a man after reduced is 45 kg
