Question

measure of third angle of triangle is_____ was other two angles are 50 degree and 90 degree​

Answer 1

Answer :-

• The measure of the third angle of triangle is 40°.

Step-by-step explanation :

To Find :-

• The measure of third angle of triangle

Solution :-

Given that,

• The two angles of triangle are 50° and 90°

As we know that,

Sum of all interior angles of ∆ = 180°,

Assumption: Let us assume the third angle of triangle as x,

Therefore,

• x + 50° + 90° = 180°

=> x + 50 + 90 = 180

=> x + 140 = 180

=> x = 180 - 140

=> x = 40,

• The value of x is 40.

Now, the third angle of triangle, We assumed the third angle as x,

=> x

=> 40°

• Hence, the measure of the third angle of triangle is 40°.

Answer 2

Answer:

40

Step-by-step explanation:

180-50-90

we get 40 so the answer is forty
