Answer:
20 degrees
Step-by-step explanation:
both triangles are co friend and 90+70=160 180+160=20
Answer:
m=30°
n=35°
Step-by-step explanation:
So the right triangle's angles are 90 and 70 so m=30° because sum of angles in a triangle=180°
since the triangle with 110 degrees is congruent, that means the other blank angle is also N.
so if the sum of angles in a triangle is 180 degrees,
110+2n=180
2n=180-110
2n=70
n=35
Answer:
90 degree's
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees
Answer:
34
Step-by-step explanation:
32 / 8 = 4
36 / 4 = 9
perimeter of rectangle = 2(Length) + 2(width)
P = 2(8) + 2(9)
P = 16 + 18
P = 34
