Answer:
d+d=90
Step-by-step explanation:
A complementary angle is equal to 90 degrees. If it is made up of two triangles (d and d) when you add them, they're total will be 90.
Answer:
It's eight
Step-by-step explanation:
32:[9x(<em><u>19-17</u></em>)-14]=
32:(<em><u>9x2</u></em>-14)=
32:(<em><u>18-14</u></em>)=
32:4= 8
Answer:
y = 50, x = 74
Step-by-step explanation:
the total degrees must equal 180. In the left triangle, we are given 80 as in of them. 180-80=100 degrees left in the triangle there are two equal angles left, so we divide 100/2 and get 50, so y=50. In the triangle on the right, there are two equal angles of 53 degrees. So 53x2=106. 180-106= 74 degrees left. x is the only angle left, so x=72
Answer:
D. 4.4x, A. (4.4)* and B. 4x.4x
