If 2 angles are formed on a line, then they make a supplementary / linear pair of angles, i.e, both the angles form 180°.
Here,
Angle A = 80°
Angle B = x°
So,
Angle A + Angle B = 180°
80° + x° = 180°
x° = 180° - 80°
x° = 100°
=》 Angle B = 100°

Answer is 48
Because 15+15=30
And 9+9=18
So 30+18=48
Answer:
105 for all of them
Step-by-step explanation:
1) take 180-75, because of opposite angles.
105
2)again, 105 because we know the opposite angle is 75
3)105
again, opposite angles.
Answer:
s = 5/4
Step-by-step explanation:
Solve for s:
86 = 8 s + 76
86 = 8 s + 76 is equivalent to 8 s + 76 = 86:
8 s + 76 = 86
Subtract 76 from both sides:
8 s + (76 - 76) = 86 - 76
76 - 76 = 0:
8 s = 86 - 76
86 - 76 = 10:
8 s = 10
Divide both sides of 8 s = 10 by 8:
(8 s)/8 = 10/8
8/8 = 1:
s = 10/8
The gcd of 10 and 8 is 2, so 10/8 = (2×5)/(2×4) = 2/2×5/4 = 5/4:
Answer: s = 5/4
Answer:
option 2, 4, and 5 are correct.
Step-by-step explanation:
180 - (20+30) = 180 - 50 = 130
Obtuse triangle is a triangle that has one angle that is more than 90 degrees and all the sides have different lengths since all the angles are different.
