Answer 1

Answer:

19th question answer is 45°

Step-by-step explanation:

90°= y ( vertically opposite angle)

y+ x + x = 180 ° ( Angle sum property)

90 °+ 2x = 180°

2x = 180 ° - 90 ° = 90 °

2x = 90 °

x = 90 /2

x = 45 °

Answer 2

$\small \green{Question:1}$

1) /_ EOC

2)AOC and BOD

3)BOE and EOD

$\small \green{Question:19}$

In question 19 to find the angles simply find the degree of 1 angle and then subtract it with 180°

Applying the method:-

y=90 as the angle opposite to y is 90°

Now,x=180°–90°/2

=>x=90°/2

=>x=45°

Number of non-fruit trees=77

A/q,Let the no.of fruit trees be x

=>3x+2=77

=>3x=77-2

=>x=75/3

=>x=25

Explanation:-

As the no.of fruit trees were 3times more than the no.of non-fruit trees the equation formed was.

3x+2=77

in the next step 2 moved to R.H.S and it's sign became - as its sign was + on L.H.s.

77-2=75

and when 3 moved to R.H.S. it was divided As in L.H.S it was multiplied.

The final answer came 25 on division.
