Answer:
it would be 2d - 60
Step-by-step explanation:
Because if you susbtract d from 3d it would be 2d cause d is like a number in this unit
Answer:
Step-by-step explanation:
We can split this into 20 triangles, each with an angle sum of 180 degrees.
So 180(20) = 3600 degrees.
Answer:
47°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180, that is
x = 180° - (48 + 85)° = 180° - 133° = 47°
Find the coefficient of x^2 in the expression of (x - 7)^5.
