Answer 1

Answer:

Q6-60* degrees

Q76-\7- 30, 60 and 90

below

Step-by-step explanation:

Q 7: Ratios of angles in triangle are 1:2:3

let x be the common ratio.

sum of all angles in Triangle = 180

ATP,

x + 2x + 3x = 180

6x = 180

x = 180/6

x = 30

Therefore, the angles are 30, 60 and 90

Q8- A=x=20°.

✓B=2x=2×20°=40°.

✓C=6x=6×20°=120°.

Answer 2

Step-by-step explanation:

Q.6 Ans: Three angles of a triangle are equal i.e the triangle is an equilateral triangle, so the measure of each angle is 60°

Q.7 Ans : Ratio can be expressed as (using a constant k) : 1k + 2k + 3k to sum up to 180°(collectively: as the summation of all angles)

i e : 6k = 180°

=>k = 30°

So, the measures of each angle are 30°, 60° and 90° respectively.

Q.8 Ans : same as Q7,

1k + 2k + 6k = 180°

=> 9k = 180°

=> k = 20°

hence, the angles are 20°, 40° and 120° respectively.
