Answer:
Step-by-step explanation:
a=180-122=58°
Let ABC be the triangle in which BC is diameter.
Diameter always make angle 90° on the circumference.
so b=90°
∠B=1/2×58=29°
29+b+c=180
29+90+c=180
c=180-119=61°
D 0.78 and 39/50 \ its logical
If your writing the equation it would be e subtracted by 5 equals 18 so it would look like e-5=18
Answer:
Look at the proof down
Step-by-step explanation:
The given is;
→ ∠1 and ∠2 form a linear pair
→ ∠1 ≅ ∠3
We want to prove;
→ ∠2 and ∠3 are supplementary
<em>We will write the proof in like a table</em>
1. ∠1 and ∠2 formed a linear pair ⇒ 1. Given
2. m∠1 + m∠2 = 180° ⇒ 2. Sum of angles on a straight line
3. ∠1 and ∠2 are supplementary angles ⇒ 3. Supplementary angles add up to 180°
4. ∠1 ≅ ∠3 ⇒ 4. Given
5. m∠2 + m∠3 = 180° ⇒ 5. Substitution method
6. ∠3 is a supplement of ∠2 ⇒ 6. Supplement of equal angles
7. ∠2 and ∠3 are supplementary ⇒ 7. Proved
