Answer:
the third obtuse angle is 110°.
Step-by-step explanation:
From the question, the 0s at the back of the given angles are meant to be degrees (°), since the sum of angles in a triangle cannot exceed 180°.
Hence, The question would be:
The two angles of an obtuse triangle are 23° and 47°. Find the third obtuse angle
.
Step-by-step explanation:
In a triangle, there are three (3) angles which sum up to 180°.
Two of the angles are given which are 23° and 47°. Now, to determine the third angle which is an obtuse angle.
(NOTE: An obtuse angle is a type of angle that is greater than 90° but less than 180°).
Let the third obtuse angle be x
Then , we can write that
23° + 47° + x = 180° (Sum of angles in a triangle)
Then,
70° + x = 180°
x = 180° - 70°
x = 110°
Hence, the third obtuse angle is 110°.
