Answer 1

Answer:

q1

One angle of a triangle measures 135°. The other two angles are in a ratio of 4:5. What are the measures of those two angles?

My dear friend,

Given data :- one angle of a triangle measure is 135° .

Other two angles of the traingle are in the ration of 4:5.

Find out :- find out the value of those two other angles =?

Let suppose that the other angle of the traingle are 4x and 5x. Then we know that, sum of the all three angles of a traingle =180°

4x +5x +135° = 180°

9x=180°-135°=45°

x = (45°/9)=5°

So the one angle measurements is 4x = 4×5°=20 ° answer.

The another angle measurements is 5x = 5×5° =25° answer.

If you want to check your answer then sum of all three angles will be 180°.

20°+25°+135°= 180° answer.

this is of question 1
