3. Among two supplementary angles, the measure of the larger angle is 36° more than to
measure of the smaller. Find their measures
Answers
☆ Given :
- The measure of the larger angle among supplementary angle is 36 more than the smaller angle.
☆ To find :
- The measures of the angles.
☆ Solution :
Let the smaller angle be x°
Thus, the larger angle will be x + 36°
Now,
We know that,
★Sum of supplementary angles = 180° ★
According to Question,
⇝ x + 36 + x = 180
⇝ x + x = 180 - 36
⇝ 2x = 144
⇝ x = 144/2
⇝ x = 72
Therefore,
- The smaller angle (x) = 72°
- The larger angle (x + 36) = 72+36 = 108°
Check :
Sum of supplementary angles = 180° (we know)
→ x + 36 + x = 180
Putting the value,
↣ 72 + 36 + 72 = 180
↣ 108 + 72 = 180
↣ 180° = 180°
Hence, both sides are equal. Thus, Checked !!
Answer:
- Larger angle is 108°
- Smaller angle is 72°
Explanation:
Given:-
- Two supplementary angles
- The larger angle is 36° more than the smaller angle
To find:-
- Measures of the angles
Solution:-
Let the smaller angle be x°
larger angle is x+36°
/ 1 + / 2 = 180° [given that the sum of angles is 180°(supplementary)]
=> x + x+36° = 180°
=> 2x = (180-36)°
The larger angle is x+36° = 72° +36° = 108°
Verification:-
As they are supplementary, their sum must be 180°
That is,
Larger angle + smaller angle = 180°
108° + 72 = 180°
=> 180° = 180°
Therefore, verified.
