Question

a. If the two angles of a triangle are 470
and 830
, what is the measure of the third angle?

Answer 1

Answer:

50°

Step-by-step explanation:

We know that,

Sum of all angles of a triangle is 180°.

Let the third angle be x.

Therefore,

47°+83°+x = 180°

130°+x=180°

x =180°-130°

x=50°
