Two angles are supplementary. One angle is 36 degrees bigger than the other. What is the measure of the bigger angle
Lorico [155]

let the other angle be x degree

bigger angle = x +36°

According to the question,

x+36° + x° = 180°

=> 2x = 180–36

=> x = 144/2

=> x = 72°

Measure of the bigger angle = x + 36

= 72° + 36°

= 108°

100 POINTS!! PLEASE HELP IM REALLY CONFUSED
11111nata11111 [884]

Answer:

1:

<A=½(arcJL)=½(70+120)=35+60=95°

[inscribed angle is half of central angle]

2:

<W=½arcVX=½(130)=65°

[inscribed angle is half of central angle]

3.

<E=½(arcDC)=½(90)=45°

[inscribed angle is half of central angle]

4.

<R=½(arcXZ)=½(110+62)=86°

[inscribed angle is half of central angle]

5.

<B=½(arc DC)=½×104°=52°

[inscribed angle is half of central angle]

6.

<K=90°

[inscribed angle in a diameter is complementary]

<K+<J+<L=180°(sum of interior angle of a triangle]

<L=180°-90°-53°=37°

again

arc JK=2×<L=2×37=74°

Help plz i need to pass
Vadim26 [7]
<span>With the information given, we can not find an answer by what angles are congruent, but we can find the sum. A triangle must have a sum of 180 degrees
so you can sum up all the choices and see which one does not equal 180

The answer is C

</span>A 180 This can be a triangle
B 180 This can be a triangle
C 182 This can NOT be a triangle
D 180 This can be a triangle
