What is the measure of angle B in degrees? A triangle has angles A, C, 51 degrees. Angle A has exterior angle B and angle C has
an exterior angle with measure of 112 degrees. °
1 answer:
Step-by-step explanation:
The angle adjacent to 112° will form a straight angle along with 112° adding to 180°. That makes C: 68°
a+c+51 = 180
a+68°+51° = 180°
a+119° = 180°
a = 180° - 119°
a = 61°
a+b = 180°
61+b = 180
b = 180-61
b = 119°

Answer:
5x+10y+5z
Step-by-step explanation:
2(3-4a) + 5(a-7) first do the distributive property
6-8a + 5a-35 now combine like terms
-41 - 3a is the final answer
5x40=200
4x40=160
200+160=360
Answer:
Step-by-step explanation:
Let the numbers be y, y+2, y+4
3(y+2)=153
3y+6=153
3y=153-6
3y=147
y=49
y+2=51
y+4=53
