Question

tell question 3 and 4 in full method

Answer 1

Question no 3
First u should know about complementary
If sum of 2 angles is 90 degree then it is a complemntary
Now solution
2:3 i.e.
Angles are 2x and 3x
So
2x+3x=90°
5x=90°
X=90/5
X=18°
2x=2*18=36
3x=3*18=54

Answer 2

Let the common ratio be x.

Let one angle be 2x and another angle is 3x.

We know that Two complementary angles add up to 90.

2x + 3x = 90

5x = 90

x = 90/5

x = 18.


The first angle = 2(18) = 36.

The second angle = 3(18) = 54.

Therefore the measure of the larger angle is 54 degrees.





(2) Let one angle be x.

Then the supplement of the angle = 180 - x.

Given that an angle is thrice its supplement.

x = 3(180 - x)

x = 540 - 3x

4x = 540

x = 135.


Therefore the measure of the angle = 135 degrees.




Hope this helps!
