The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle
solve
115+z=180
subtract 115 from boths ides
z=65
answer is third angle=65 degrees
Answer:
127 ft
Step-by-step explanation:
split the square diagonally and use the pythagorean theorem
Answer:
m<C = 56°
m<D = 124°
Step-by-step explanation:
Of CDEF is a parallelogram then the sum of angle m<C and angle m<D must be equal to 180°
4x + 28 + 17x + 5 = 180 add like terms
21x + 33 = 180 subtract 33 from both sides
21x = 147 divide both sides by 21
x = 7 now to find the measure of each angle replace x with 7
Answer:
B is the right answer
Step-by-step explanation:
because of negative 7 on the right it shows that it is down 7
